Edgars are *****ed

I am Mpolokeng Mthivane. I bought clothes at Edgars for years and my account was closed by 2019,beginning of 2020 started a problems. I started to receive numerous calls a day from different debt collecters demand that I pay my account or the will black list my name. Only to find that they demand money for insurance that I never open with them in the first place. They are still harassing me even now I don't want anything to do with Edgars, they even close customers service you will get this cell numbers that will ring without response
