Payments on accounts

The week of the 15th of November I went to Wellington MTN store - showing them the message I received from MTN that my account is behind. I showed them the screen shot of my bank statement and they activated my phone again the next week of the 20th of November the same story and I provided them with the proof of a bank statement of payments made - they logged a query and also send my debit order - on Tuesday 21 November again my service was closed and I went to MTN malmesbury and they told me the 2 October and the 27 October payments to not register on MTN data and again I provide all the proof I need of each months payment- today. 2 December MTN debit order of R1334 go off taking 3 installments and all the ladies at MTN say is I am only a consultant I do not work with this type of issues - I ask them when will this me resolve and they say I do not know - now they claim I provided them with the wrong reference but they swipe the payment of the 2 October on the eft and that also do not register . The lady told me when the investigation is completed I I do get my money MTN will keep that for future payments. I feel like they stole my money and I have been a customer for very long. But my trust is broken lucille Behm
