Telkom mobile oversell and no delivery

My husband and I decided to switch to a Telkom Free Me Family contract, effective 1 May. We researched coverage and all seemed good. We jumped through all the hoops and finally got both phones ported around 9th of May after several visits to the shop and the calls to call centre. The inefficiency and lack of full information was mildly frustrating but we got there. The point of the family contract is that there is 30 gigs of data that can be allocated by the main SIM holder to other family member SIMS. Great product right? We are now 14th June and no-one has been able to tell its how to do this. We have been charged R200 for data used on my phone when there are well over 25 gigs of data unused on my husbands phone. We got a reference from the call centre and someone called me while we were travelling and asked for feedback. He sent me an email (as we could not go through the process while on a road trip) - we tried following the instructions on the email but were blocked out ("we cannot get this information at this time, please try later"). We sent a feedback mail back saying what had happened and in response got a case closed SMS. We then spent well over an hour in the shop in Knysna during our holiday - they were not able to sort it out. The staff at the shop had been instructed to use a short code to allocate data - it returned an error message. We had previously tried this method. We also tried the app while in the store, also with no luck. After this I set out all the information, along with the error reference codes and emailed it to the agent at Knysna (who was genuinely trying to help). Her manager called me back and told me she was escalating the matter. We then got another case number. When nothing happened on this we called the call centre - AGAIN - and were told that they have up to 9 days to close a case (despite the email with the reference number giving a time frame of 24 to 48 hours for a response). We said that this was unacceptable as by now the situation was a month old. So we were sent ANOTHER reference number. Then on 8th we received two emails - one for each of the outstanding references saying "Your request was attended to by our support team". But no-one contacted us and nothing has changed - I still cannot get data on my phone and the app still returns the same message. We will probably have to spend another hour or two in the shop with no guarantee of a resolve. If anyone from Telkom is interested the case numbers are 974521, 974858 and 950988. You have my phone number and a call would be greatly appreciated.
