FNB CONNECT HORRIBLE SERVICE!! DISGUSTING BEYOND WORDS!!!!!

I am truly disgusted with the service received from the FNB Connect department. I agreed to a Simcard contract Oct 2015 which was explained to me to be a 24 month contract. In Nov 2017 my account was still debited for the simcard and every month since. I have tried contacting the department's call centre on ********** numerous times only to be cut off after holding for 10minutes. In July 2018 I sent a formal correspondence requesting that the account be cancelled immediatedly and that I did not agree for it to be reoccuring. I received a correspondence under reference CRM: ********** ********** 0 confirming the account being cancelled, only to find my account being debited again and again. I received a letter of demand and spoke to Nompumelelo in the accounts department, and settled the account in full. Afterwards i again called FNB Connect call centre only to speak to a lady who can not even speak proper English and is extremely unprofessional!! after requesting that I want a correspondence that this account is now closed, cancelled and the debit order stopped, she merely put the line on hold for me to get back to the " selection of options" to be transferred to department. This is disgusting DISGUSTING HORRIBLE service!!!!!!!!! All I am asking for is a correspondence and NO ONE can assist me. But boy, can they quickly threathen when payment is not received.!
