PASSING THE BUCK

I received a call from a man at Summer Mobile who knew that I was due for an upgrade and would I like to do this telephonically and the new phone would be delivered by courier in 7-9 working days. I said yes and chose the Samsung S9 for a 3 year contract. After waiting 7-9 days without any sign of the delivery I phoned MTN who transferred me to Summer Mobile as they said it had nothing to do with them. A women at Summer Mobile said that she would cancel the upgrade as the courier service had returned the new Samsung S9 as my Contract was still in my previous marriages surname. My ID number is the same and my P O Box Address is correct and after being with MTN for 22 years they are now questioning my surname which was supposed to be updated 20 years ago when I changed my PO Box address after getting remarried. After phoning MTN again and visiting the Fourways Mall store I was told that the system says I am on a 3 year renewed contract on the system and have received the Samsung S9. MTN says they have nothing to do with it, Summer Mobile has to sort the non delivery of the S9 out. I am still waiting for the lady from Summer Mobile to return my call after leaving a message for her to phone me as she wasn't picking up the call. I am paying for a contract for an S9 Samsung which I haven't yet received!!
