Unhappy customer

I have been a loyal customer since they were called Early Bird. They have a very poor record towards customer care and feedback. About 3 weeks ago they collected my LG Plasma TV for repairsdue to blurring screen. My TV is on contract for 8 years and this is the first service I placed. I had no feedback from their service until I called them week later to be told they cannot fix the unit and would like to deliver it back unfixed. Also told that someone from finance will call me to offer me a rebate of R200 on my next installment. A week later I still did not hear from anyone at Master Care. I called the service to request to be put to the manager or finance. Nobody called me and finally I got to Mr Niren from finance. All he said to me was that they cannot repair the TV and according to their policy may return the unit unfixed with about a R200 compensation. I requested to speak to their manager and until today nobody called me. I feel that their customer care does not exist. Secondly the debit order did not go through on the 1st of July. On their run it went through on the 24th July. Then on the 1st August and the 1st September they did a double deduction without my authorization. Mr Niren asked me to send him bank proof and I forwarded him 3 transactions the same day and asked him to acknowledge my mail which till now no response from him.
