Telkom *****ing money from customers.

I bought, and paid for 20 gigabytes of data online from telkom - the transaction went through, the money was paid, no data was delivered. I got an SMS on my modem a few hours later with the following message 'Dear valued customer, we received your recharge request and apologize for the processing delay. Your reference number is [***]. Kind Regards, Telkom.' That was a few days ago. I went into their Centurion branch to try to sort this out, the staff were very friendly though they stated they could not help me as they had never heard of that reference number before@ Then they gave me an in store phone to speak to the help line. After an hour of sitting on hold, I left the store. I have phoned 081180 a few times at random throughout the day and night, each time sat for an hour waiting for a consultant, nothing. What now?
