Do not activate my new contract sim card

I have app**** for my new contract on Friday 8th May and was approved and told delivery will take place on Monday 11th May. That did not happen. I received my tablet on Tuesday. I phoned in around 12 to activate my Sm card. The lady said it would take up to 14 hours. Ok that would mean by 02:00 on Wednesday morning it would work. And what do you know its still not working. At 08:20 on Wednesday the 13th May I phoned in again regarding activation and the guy told me that no activation was logged but he would do it immediately after holding on the line for what was like 20min he said that his system is very slow and that he would attend to it. I should take out my sim card and wait 3-5 hours and re insert and should work fine by then. Look at the time its 4 and half hours and still not activated. Oh but they are very quick to call when you owe them.
