855-222-8463

Called two days in a row, both weekdays, mid-afternoon. I didn't answer. No message left. If they call today that'll be 3 in a row.

Called repeatedly. No message left. Blocked them.

seemingly unstoppable calls daily from these creeps. Never answer.

They called me 3x 2

Every time I pick up the phone and say hello they hang up they probably called my phone a dozen times

Same number has been calling for days, three times a day.. Just called again at 5:24 E.D.T

Call with no message. You call me and then don't identify who you are? Can you say...call block?

Keeps calling and leaving the following message:
"We're calling to assist you in the return of the unused Comcast equipment Comcast has partnered with complete recovery to make the return easy for free return options or questions contact us at 855-222-8463 and reference account to 364-4539. Thank you."

They called my cell phone number and left the same message about unused Comcast equipment and working with Complete Recovery.  The number that showed up on my phone was 317-981-2675.

This number calls me 6-8 times per day. No response when I answer - never leave a message.

They call multiple times a day, saying they want me to return Comcast equipment. I blocked the number

Same issue with Comcast equipment.  I am tired of this group.  They use other numbers as well.  They hang up if you answer.

855-222-8463 called twice today. After 11am and leave no message.

8552228463called twice today, saying something to return, and asked me if I lived a address she said.

Started getting calls from this number 18 months after cancelling Comcast. They insist that I need to return some equipment that I never had in the first place. Some kind of TV signal converter that I never had because I only had Comcast for internet. There was a basic TV package that was thrown in a bundle, but I never had any equipment for it, or had it hooked up to my TV.

I suspect (but have no proof of) that this may be a legit collection agency, but they are useless. They told me that calling Comcast and working it out with them is the only way to get them to stop calling... That sounds super easy. Calling a megacorp to deal with an account that was deleted 18 months ago. Nothing like dealing with people that are following a script, think you are lying because of a database entry, and don't care about it to begin with.

"They told me that calling Comcast and working it out with them is the only way to get them to stop calling..."  They lie like a Persian Rug.  That is not the only way to get them to stop calling.  A certified, return receipt debt validation letter will do exactly that.  A cease and desist calling letter will do exactly that as well.  Making them follow the letter of the law will help also:

It is incumbent upon them under the law to prove that the debt exists and that you owe it, and (this is the important part) that they have the legal right to collect it.  You are not obligated under the law to prove that you don’t owe or that it is paid. 

Federal law (FDCPA) requires them to send you a letter (US MAIL ONLY) postmarked within 5 days of their first contact that contains their name, physical address, the creditor’s name, and the amount of the alleged debt. It also must contains “mini-Miranda” telling you that it is an attempt to collect a debt and that all information will be used for those purposes.  The one other important thing that this letter must also have in it is that you have a right to dispute the debt within 30 days of receipt of the letter and if you do so, all collection activity must be stopped until the debt is verified.

First, you should make a complaint at this Federal Agency, and while there you should also read up on how debt collection is supposed to work as well as what your rights in this matter are: https://www.consumerfinance.gov/

Also file a complaint with your State Attorney General's office.

Calls me 5-6 times a day while I am at work in an 8 hour period. EXCESSIVE!!! Never leaves a message, I blocked them and they STILL call!!

Comcast calling regarding returning equipment after cancelling services.  The guy that I spoke to was very friendly and just wanted to make sure I did not get charged for the equipment.
