MTN *****s money from cunsumers

29 February 2016 , i was debited -+ R1067.00 by MTN and i don't have account or SIM with MTN . The last time i had contract or MTN SIM was in 2006 . i went to my bank and they told me the dibit was from MTN , i explain that i dont have MTN SIM and they reversed the debit order and told me to go to MTN to check whats going on. i went to MTN greenstone branch and asked what was happening and i was told that there was 2 active phone in my name opened in January . i told the lady that i know nothing about any MTN contract and i've been using Cell C since 2006. i was told that if i know nothing about this i must bring affidavit confirming that i have not opened an account , copy of ID , page with my signature and proof of residence and she said they will suspend billing and SIMs .on 01 March 2016 i submitted documents and my cell C number and i was told that someone will contact me within 21 days . i didn't get any call . on 01 April MTN debited me R4300. i revesed the payment and went to MTN festival mall was told they cant do anything about this and i must just keep on reversing payment . This is affecting my good credit and i need this to be resolved ASAP. PS: i never lost ID
