MTM not honoring SAMSUNG deal as advertised!

I upgraded my contract 7 September 2018 from MTN Kenilworth Centre for Samsung S9 as per the ad to be received with 64G memory card. The handset is unwrapped in store by the assistant while she throws out the wrapper & instructs me I should receive the memory card within 7 days. I dont hear back from them so I enquire. I'm then told to look at the wrapper for the voucher number & redeem online. I let them know they threw it away in store & made no mention of it when they unwrapped the handset! I'm then told there is a new process & emailed instructions to redeem online. When I alert them to the instructions s that claim there are steps they need to cover as the seller they then claim "Samsung is giving them the run around" & they will purchase 1 in store & I can collect. 9 Oct I'm told it'll take 1-2 weeks delivery. 3 weeks later I enquire & am told they are awaiting delivery. 6 Nov they then ask for coupon details that had been SMS to me. They NEED IT they said! I forward that on & after they receive they tell me to send it to samsung rewards. I then email back & let them know it makes no sense. 8 Nov I'm emailed back "The fault is by Samsung they are delaying everyone deliveries they wanted the clients to email the coupon To them ,but they didn’t tell us . Sorting it out." I AM STILL WAITING!!! 2 and half months after I signed the upgrade & have been honoring the monthly contractual fees MTM & SAMSUNG have not honoured what they have sung in their ad!!!!!!
