5 months and tablet still not connected

During December my husband upgraded on his Vodacom contract and we decided on one of the deals advertised in their booklet where you receive a Samsung S4 mini AND a Vodacom tablet WITH 500MB data on a monthly basis. We received the goods and were told that the tablet's data will be connected at the end of December. Until now nothing has happened. Numerous phone calls were made to Frankie and we were promised that it will be connected. At a stage we were informed that the deal was actually not available as an upgrade deal but since its their fault they will continue with it. In the mean time we are paying our contract every month but are not able to use the tablet. Last week I phoned Frankie on Wednesday and undertook to phone me back the next before close of business.....no call received. On Friday I phoned in and once again spoke to Jacques as Frankie wasn't available, upon Frankie's return whilst speaking to Jacques i was transferred to Frankie and I was told that he had send an email again, as it is the case everytime I called, and we should wait. I then asked to speak to Jacques again and Jacques informed me that Judy/Julie Wolmarans***ner) will call me back....nothing
