False adverti*****t - Desperate MTN "Bozza Network"

The contract that i took on Dec 2015 was due for an upgrade and on the 23rd of August, i've received an email from MTN stating that MTN would like to reward me with 10GB per month for 24 months, if i upgrade my contract before the 27th of August 2018. The personalized exclusive offer was available in store (via Contract Advisor) or call MTN Direct on ********** 667. Went to MTN Store (Mall of Africa) and i was assisted by Mbavhalelo Mufamadi to upgrade my contract. She got an approval from her manager and my upgrade was approved within minutes. i immediately checked my balances to verify and noticed that the promotional data wasn't loaded. She logged a query with MTN that was closed by *********** consultant without feedback. I had to call them and find out why and i was told to log another query and should wait. My second query was closed aswel without feedback and after that i started sending emails to ********** and ********** and got useless replies from Nokhuthala Khoza and Maphefo. They kept telling me that my query has been escalated to system support department and its been investigated. The queries were closed aswel without proper explanation. The last email that i got from MTN was from *********** Thobekile Mkhize who forwarded my query back to Mall of Africa store.

I feel like MTN is treating me like a fool because now and then they would just open and close queries as they please and even if you call them they would give you useless answers. You guys should give me everything that you promised because i followed the correct procedures and i have proof. Learn to treat customers with respect or this was a trick to keep people on your network?
