Upgrade gone awry

On 16/02/2015 I upgraded telephonically from the Telkom Simple (R399.00) to Telkom Simple Plus (R499.00), with double the data available at twice the speed. On the day of the upgrade, I was informed that it would take no longer than 48 hours to upgrade. Ever since, we have been struggling to get the upgrade. Our account for Feb. was ? R1300.00, and we declared a dispute, because we were supposed to be charged pro-rata for the old plan, and pro-rata for the new plan. We visited the Telkom shop in Potchefstroom twice to try and find out what was going on with our account, no success. A dispute was declared, and also an escalation, to no effect. Other interventions, 2 phone calls to call centre, 2 surveys completed where we indicated that we were unhappy, and also feedback given during a survey call. So, today I get a call from the call centre to tell me that the feedback on my escalation is that I must report a fault. I asked why because the dispute was not just about the speed that was not faster, but also about the increased data that I do not have access to. The long and short...I have 2 accounts with Telkom, and my service was never upgraded. I am at my wit's end.
