MBD COLLECTORS

I have a serious concern with MBD collectors from the beginning of the year (2023) i m receiving calls almost everyday sometimes 2x a day asking for a payment on a Foschin account and i never opened an account with foschin in my entire life i keep on telling the consultants that the name and surname can be the same but not id my id number is not the one they have on their system but the names are the same .Consultants even threated me that i will pay for all the calls, I went to Foschin Alberton to check if i have any account with them but there is nothing when they check with my ID but the calls are frustrating me everyday. please help
