833-262-4528

Attempted to block this number, my phone said the number was invalid.  ???

Two more calls from this number, yesterday and today.  Tried to block AGAIN, but number is "invalid".  Can someone, anyone, please tell me how to block an invalid number???

before you drive yourself nuts.....
don't answer it!!!

I called it back and the guy who answered said "Quest Diagnostics".

Got a call from this number claiming it was Quest Diagnostics regarding a bill, but i immediately hung up and blocked the number because they called at 8:45pm and that seemed really suspicious since companies don’t call for payment methods right off the bat so late at night.

they call every morning around 8:15 a.m.  when I ask why they're calling they mumble something and hang up.  Has to be spam!!

We have had 5 phone calls to day and it's only 2:11 PM. Three different numbers! One said they were a loan company. I don't recall needing a loan! They are all recording! SKPYE has called 2 times and a 202 number 2 times and ths 833 number! This is getting OLD and needs to be looked into. These people need to be arrested because they are nothing but scammers (THIEVES!)

Called at 845, when I asked what it was about the service rep was extremely rude and asked why they called at 9. She then said I was rude. Don’t know why quest calls so late

I declined the call, they never left a message (which usually means telespammer) and then blocked the number without a problem.

I just missed a call from this number on my cell.  No voicemail. What’s weird is that I just set up a payment plan through quest diagnostics by calling the number on my bill yesterday but I called from my work landline phone to set up the payment. The woman at Quest told me I would be getting a letter in the mail to respond to with payment methods with the new amount owed listed. She didn’t even ask for one over the phone then. If this is a scammer trying to steal payment methods they are very savvy. DO NOT ANSWER.
