Foschini lack of service and follow up

Worst service ever - bought a new cell phone, was told they have to activate the sim card instore and RICA, (also for insurance ) this was not done card has been deactivated. (MTN confirmed the card has not been Ricad or activated) was told insurance will follow up as we had to text a number while in store and this was not done either, it has been a month NO return phone calls NO insurance NO working sim. have made more than my fair share of calls to TFG and nobody ever gets back to me WHY?????????
