Much to my surprise the debit orders have continued to be deducted . more than R4000 has been deducted. Customer care on 082135 couldnt assist and provided me with an e-mail to which I explained the situation and provided proof of payment. The e-mail eturned udelivered as an invalid adress. I called again and was provided with another e-mail. Again it returned .Another call and new e-mail, it delivered and went unanswered from SEPT 2019 TO 2DEC when i sent a reminder. STILL no reply. THE DECUTIONS CONTINUE , WHERE DOES ONE GET ASSISTANCE. WHY can you innititate a deduction and new contract on the phone but when it comes to cancelation time you are thrown in the non returning e-mail. the line hasnt been used , since cancelation , the full contract has been paid in andvance on cancelations , tousands have been deducted and no refund is forthcoming PLEASE HELP
