SIM activation overdue

I upgrade my contract on 1 August 2015 at The Glen MTN service centre. I was told it takes 2 - 24 hours for the new SIM to become active. After 48 Hours my new SIM is STIL not active. My old SIM however stil works. I have made 5 calls to the callcentre yesterday 3 August and was told they have raised a query and it will take 2 - 48 hours to resolve. I find this unacceptable. <br> <br> In the mean time my Data bundles have run out and I am not able to purchase any new bundles which means I am now also consuming at out of bundle rates.
