Numerous phone calls ( early morning thru late evening ). Caller ID says XXXX service ; numbers have been blocked ; but they still call. I do n't answer - do n't know " them '', did n't ask then to call me, assume its scammers. This has been going on for 18 months. Local phone provider says " Oh, too bad, not our problem. " Today I reluctantly called them ( after being called at XXXX last night ) and told them to leave me alone. They are : Pioneer Credit Recovery, IncXXXX I read the riot act to someone claiming to be XXXX XXXX. I asked what scam they are running. Please investigate these people and their " debt collection '' techniques.
