its a collection agency!!

I'm tired of this dumbass company or scammer calling 3 to 4 times a day, seven days a week, 365 days a year. Calling before 9 a.m. and sometimes after 9 p.m. If this is a collection service i do not pay over the phone. if i owe someone something send an invoice and it will get paid.

I want this person not to call me any more!!!!
