No Data and Connectivity Bill Up to date

My debit order went off on 27 July for a data contract. My service is still disconnected despite sending proof of payment with a stamp from the bank that it went off. I have spoken to more than 7 customer service agents, Went into The Glen shop twice with no help. Sent various tweets to @TelkomZA and @HelloTelkom, nothing has come of it. They keep saying we have escalated the matter but nothing has happened. I am due for an upgrade and I think I might look elsewhere because of this inefficiency. I deserve better from them.
