We get daily calls from phone number XXXX. They claim to be from a debt collection agency 'Central Credit Services '. They instruct us to call a different number ( XXXX ). We do not owe a penny to anyone and have an excellent credit score to prove it. I just want these calls to stop. I am afraid to call the XXXX number because I have read online that it is a scam to obtain personal information. We have had the same telephone number for XXXX years so I find it hard to believe it is an innocent mistake.
