Poor service

MTN call me on the 24th of November 2017 offering me a promotional package for black Friday. They said I Will be getting 30gigs of data for R199 for 24 months which I am not getting and have been try to resolve the query from December 2017 but nothing is happening but they are talking my money monthly. They then gave me a number( ********** 241) to call cause they are saying the deal was done by the third partners but still nothing is happening,cause they are telling me to speak to 808 and 808 said I should talk to MTN direct but mtn direct said they cannot help me because the contract wasn't done by them.
