I want my entertainment pass and my 20gigs anytime Data

I app**** for an upgrade with mtn, I told them I don't want their data services, coz I don't see the use for 350mb in a month, however I asked them to offer me either only an airtime package or a minutes package, they offered me a package with 100 minutes each month, however, for the 10 years I have been with Mtn, I never had any problems when I upgraded, I upgraded on 4th December 2018, now. When you upgrade you get 20gigs, and 14gugs entertainment pass, that lasts you for 30days, that I did not receive, I went in and out to the branch, they can't help me I called 135 they can't help, they confirming that the branch is not cooperating. It has been 2 months, they don't have the decency to follow up, I'm sending the agent messages to follow up, but all I get is excuses, I want my entertainment pass that is due to me when I upgrade or take out a contract with MTN, I sent my contract to 135 call center agent, still nothing, I just want what is due to me and when I do I'll change my network, and I'm taking matters further.... The packages already sucks....
