***** on Miladys account

My mother opened a Miladys account in April this year after being pressured by the staff at the shop at Liberty mall Pietermaritzburg. She had a gift voucher to buy with and didn't use the credit in the opened account. Later she received a statement that she was buying airtime with the account everyday from the 11th of May to the 15th May which does not make sense. This has been happening throughout since the account was opened. She now owes more than R 1000 of which she has never used. She has never bought anything at Miladys but have been paying installments. This was reported at Miladys and we were told to send an email to : *** which are not delivering. This is a ***** and it seems like no one wants to help.
