*****ing money from my account

Unfortunately this is my absolute last resort. I have phoned MTN 10 times in the last 3 weeks I have been on hold a total of 4 hours with absolutely no response, The people in the call centre don't give a damn they make empty promises and will not help you. MY cell was cut off the mtn network the 24th may for no reason in the time my number was disconnected data was charged for in that time for R1849 I could not use the data as I was not connected at the the time to the network. I then paid in the outstanding amount excluding the queried data total I have refrence numbers and I paid my July statement in advance. But regaurdlless of all this MTN still took a debit order of R2474 off my account without my permission putting my account into credit but im told my debit order for july statement will still go off even though the amount is paid. I can not cancel my debit order nor can I stop MTM from taking money off my account even though I have lodged two queries submitted 7emails and have 7 refrence numbers. No One is willing to help me and I am now beyond frustrated with MTN
