Foschini has the worst Customer service

Went to purchase something only to find my account has been blocked. I have been handed over due to no payment according to them. I have been paying each month and receive no calls or emails in this regard. They said they couldn't call me as I never answered but they added an extra digit to my cell number and still argued that 11 digits are correct. I have no words!!! Further they expect me to pay the legal fees as well. I think they are sadly mistaken. Their lawyers also couldn't give me a statement on how the amount that I owe is made up of. Now I have to wait another week or whatever. Absolutely ridiculous
