My manual payment has not been processed STILL

A telkom mobile debit order failed due to account problems i was experiencing, and as a result I had to make payments manually. <br> <br> I made my payment via internet banking on the 13th of March - but still the amount paid in was not processed. I called Telkom Mobile a week ago to inquire about this when i received communication that I still had not paid, and the agent told me that indeed my money was paid in and that she'd escalate the matter so they could clear it. <br> <br> She gave me a case number: ***1.<br> <br> Today I'm still receiving messages from Telkom Mobile saying I owe the money. I called in and the agent (Ntsako) was no help whatsoever! <br> <br> I'm only in arrears for this last month, and not the month prior to that - and the reason I'm in arrears is because the debit order was not run this time around. The first time I called in about my query, the agent said the debit order would be run as soon as the money I paid in manually was cleared. <br> <br> I don't appreciate being taunted with messages about me being in breach of contract when it's beyond my control!
