Unresolved Query

My contract ended in July 2015, without notice, or offer of renewal, they kept deducting different amounts ranging from R196.85 to R210, September was R110, why I dont know I have made several enquiries wheras the consultant said it will be stopped in November, to my surprise ,the debit order went off in Decembet again,upon which I have made two enquiries ever since demanding all my money back from August till December and they said they would call me back, that was 16 December, up until no one has contacted me, this is pathetic after 3 attempts from my side still no luck, this better be worth the wait , MTN owes me more than R900 , I am eagerly awaitibg your urgent response.
