UPGRADE WENT WRONG

Mondo guys phoned for an updgrade on behalf of MTN as they claimed upon my initial contract quilifying upgrades in Oct 2020 only to find they delivered a wrong device and when I call them l was advised to take it back to the nearest branch of which is Limpopo Mall Of The North MTN, and this was Oct 2020 and they have been deducting the money since then hence l am not in possession of their device. I have been calling, sending them emails with no luck of help. That means l have been paying for the devise l was never in possession of from Oct 2020 to date.

I don't want anything to do with them at all costs because they are basically infringing into my personal financial credentials.
