BE VERY AFRAID OF MOBICRED

Have an account with these sharks.Been trying to update my contact details for over a year now,no luck at all,i've done a facial profile,you know the selfie thing/send copies of my of my id,phone call centre,can't remember how many times,and still i'm awaiting for their response.***********,that's all it is.Owe them R869.16,installment R100,interest R11.85,NOW HERE'S THE SNAG R57.00 MONTHLY FEE???R31.15 goes to my account.Monthly fee for what,i can't use this account,because they are to *********** to change the old cell number to the new one so that i can receive the OTP when buying online.This has been going on for the past 18months.They will keep on deducting the so called monthly fee until my account(869.16),that's about 57.00 for another two years,on top of the interest and initial monthly installment.I've now decided to pay them the full outstanding amount and ask them to stick it.....you know where,imagine 18months without any response,be afraid,very afraid.
