What is Vodacom doing...sim not connected for 3 months!!!

So I upgraded on the 6th of February to a different package with a Samsung Core and to sweeten the deal included is a Vodacom 10' tablet with 500meg for free. Phone works well and happy with it, BUT I HAVE YET TO BE ABLE TO WORK WITH THE TABLET SINCE DAY 1. Phoned the shop (Vodacom Heidelberg Mall, Beliena)...almost every day...every week...every weekend visited the shop...every time they have sent the mail again for the people working to connect the tablets sim...until today NOTHING has happened and I can not use the tablet. Phoned Vodacom 082 111 number and spoke to about 8 to 10 people...the end of every conversation they tell me I have to go back to the shop where I did my upgrade and they have to do the connection...HOW CAN I DO THAT IF "THEY" CAN NOT EVEN HELP ME?????? IS THERE SOMEONE OUT THERE WHO CAN ASSIST...GETTING GREY HAIR AS I AM TYPING!!! PLEASE HELP VODACOM????????
