MTN 30GB Promotion ......Lies!

It's been almost 4 weeks since i did my upgrade with the promise to receive 30GB promotional data. To date I have not received anything from MTN, I have made several enquiries, all resulting in an escalation and still nothing! I am constantly being told by the call center that the department responsible for this has been informed and i should allow 72 hrs for response, well its been 4 weeks MTN!!!
