Unkept promises and passing the buck

good day,<br> <br> i was instructed and had the LTE sim card delivered to me by MTN for me to swap to LTE. I further received an sms reading \Y'ello! Still havent swapped to MTN LTE SIM? If you swap to an MTN LTE SIM you will get a FREE 1GB Data Bundle to enjoy". <br> <br> I swapped on Friday the 8/05/2015 and i was told by a call centre agent that the 1GB will come in after 48 hours that is Sunday 10/05/2015. On Sunday night i called and Palesa from the call centre advised me that i was given incorrect information the right turn around time is 72 hours which makes it Monday 11/05/2015. <br> <br> on Tuesday 12/05/2015 I called again and i spoke to Thapelo Molekwa who funnily told me that there's nothing the call centre could do"
