PROMO OF 30GB NOT YET RECEIVED

I did a new contract with MTN on the 13th of November 2015, and part of the package includes a 30GB data bundle, I haven't receive this yet and it is 2 weeks now. Every time I contact the store they tell me they will call and then the query only gets escalated, I also called 808 about 10 -15 times because the MTN store keep referring me to them and when I contact 808 they say they cannot do it for me I must call the MTN store, so every time they refer me to someone else. This is getting ridiculous because it was part of my contract and my first instalment is going off on the 1st of December and I haven't received my package.
