Please open my channels as you can see my payment

Bad service ever, made the payment using my bank app on the 30th of June. Called to open my channels and even forwarded the proof of payment. My channels were opened after, to my surprise today my channels were all locked, got sms that I need to make payment. Called in to be assisted, was on the line for more than ten minutes holding for the gentleman to allocate my payment as he can see my payment that side, call cut while I was on the line no call back. Had to buy another airtime told the second gentlemen that I don't have enough airtime if the call cut please call me back. Nothing as yet no call back my channels still locked. Bad service ever serious, I work with client and I know how to treat my customers.
