Blocked channels

I have paid my account on 2nd of October but on the 8th of October they blocked my channels saying that they didn't received my payment, I call them and they suggested that I must go to capitec to fetch proof of payment because I used masterpass capitec app to pay and I emailed the proof and they helped me after 4 days they blocked the channels again.. I phoned them several times but they failed to help me and their services is poor, yesterday she even dropped the call after considering it was me again
