Upgrade not worth the frustration

Upgraded to new contract on Black Friday special @MelroseArch MTN on Monday 2 Dec. Requested Samsung S10. Nothing fancy. Now Tues 10 Dec and STILL NO stock. Nobody can tell me when i will get my phone, at this rate i will be lucky if its NEXT YEAR. Also the special came with a TV if you are the first 500 customers. I will be lucky if i am part of the first 5,000!!!! Really ****py service and MTN could not be bothered to keep current clients happy, just get told its head office problem not the branch. Remember without us YOU are NOTHING. When will i get my phone???
