Upgrade and no phone

I requested an upgrade on 16 April 2015 and all was well and was charged for the upgrade same time. A week later no call from courier not Mtn and I contacted Glasson who was helping me with the upgrade. I cannot port my number because the next upgrade is 2017 and I have now paid for a new phone and new services that I really don't have. It's now the 05 May and after numerous emails and calls to Glasson Markham my issue is still not resolved. It's funny how mtn can take money out of your account and not deliver. Every week my phone is suspended because of a limit that they imposed on me. You sit 30 minutes every time you need to speak to them. This is unacceptable and want all charges reversed and upgrade cancelled. I want to port my number to Telkom Mobile
