lack of customer service

I app**** for a life cover with Discovery in Aug 2014,after medicals I was accepted in Sept. My first debit order due to go off in Oct. end of Sept a debit order went off my account which I stopped as this was not the arrangement. spoke to the agent who assisted me(Tshepo Marong),issue resolved after some back & forth and next debit was due to go off in November.debit did not go through.more back and forth we agreed that in Dec there will be a double debit. Dec no debit goes off. I call in Jan when back from leave and was told the debit order was stopped hence they couldn't deduct. I contact my bank who provide proof that the debit order was reinstated on 23 Nov so the debit should have run. meantime Discovery decide to double debit me in Jan before I receive feedback as to why I was not debited in Dec, this debit I stopped as well as discovery had no right to double debit without my authorization. To this day between Fazeela Lessing,DL_Credit-Control & DSIEscalations I have been emailing every two weeks asking for feedback and my emails are not even acknowledged. I refused a outsurance policy in favour of discovery.I email every two weeks for feedback and still nothing
