800-969-6808

I have received 12 calls from this number with the first one starting at 8:30 a.m.  It is now 11:00 a.m.  This is extremely successive.  I was two days late on my wells fargo credit account in the amount of $19.00. I paid the bill online yesterday but I am still being harrassed.  I have read that the people associated with this number are not actually Wells Fargo but a collection agency.  The tactics being used to collect $19.00 are excessive and against the law.  They never leave a message when I let the answering machine answer.  Then they also started calling my cell phone number too.  I am on the do not call list and don't owe this particular organization any money.  My debt is owed to Wells Fargo and has been paid.  What are my options to stop these calls?  I refuse to talk to them.  I would like to report them to the police..will this help or make it worse?  If anyone has advice I could really use some.  Thanks
