Disappointed new LTE contract customer

I signed up for an LTE contract almost three weeks back. Three days into using my data it surprisingly ran out. I went to the Telkom store in Stellenbosch Eikestad mall, where the consultant agreed that only half of the data i was supposed to receive was allocated to me. She subsequently logged a call, reference number ********** 4, on Monday, 10 July and advised me it would be resolved in 2-3 business days. On Saturday, 14 July my call was not yet resolved and was advised it had only been allocated to an agent the day before and should expect some joy on Monday. Up to now, a week later, nothing appears to have been done. In the meantime we have no service even though we desperately need internet services for entertainment and work purposes. The consultant i spoke to on Saturday even said i should not come to the store to follow up on faults, but should rather call the call centre...which i tried with no luck because of excessively long call services. As a new customer, i am very disappointed and am contemplating cancelling the contract altogether.
