MTN don't listen

As a client of many years standing with MTN I now have a formal complaint about the staff at The Glen. I upgraded my phone on the 22nd July 2020 I requested that the phone have a minimum 32Gig Memory. I purchased a CAT S31 only recently to realize that this phone only has a 16Gig Memory. NOT WHAT I ASKED FOR! Please note that nowhere on the packaging or on your advertising does it say 16 Gig. Apart from this I regard this phone a a hunk of junk as it is slow a difficult to use. None of the problems were explained to me and you only have to look at the reviews on this phone (Which I only did after having problems with it) The CAT S31 is not a good phone and has progressively got worse and I am now using my old phone! MTN should ensure that staff are trained to listen to a client's requirements.
