Disregard for the elderly!!

Never have I been disrespected nor has my safety been disregarded in this manner!!! As an elderly person under the current Covid 19 epidemic the staff at MTN carnival mall have had me go back and forth with numerous times for a matter that should rightfully come with a phone replacement period!! I took out a contract in March 2020 and 4 weeks ago my phone just stopped ringing when calls came through or if it rang it would not give me the option to answer the phone thus placing my family and friends under distress because they could not reach me. on the 5th June 2020, I then went to a MTN shop in springs town where a friendly lady checked the phone and informed me it was a technical problem and advised me to return the phone where I originally purchased it so they could give me a new phone seeing as my contract was less than 6months old. On the 8th June 2020 I then headed to the MTN shop at Carnival Mall where Nancy Msholo assisted me and advised my old sim card was small and I needed to do a sim swap of which they charged me R115 for what I believe should have been done when I took out my contract if the sim size was an issue. No mention of such was made when I took the contract. I still had the same problem when I got home and found I had lost all my contact numbers.I went back the following day where a lady named Mahlekgaphi assisted me. she advised me to return the charger and earphones in order for them to further assist me. I received an SMS with her name advising she assisted me. I then returned to the shop the following day 10th June 2020 where a very arrogant man had the phone checked by the technical agent who said the phone was working and I must switch it off and charge it when I get home . They did not show me how they had fixed it or if it was working. When I demanded a new phone and threatend to lay a complaint of poor service the man proceeded to tell me to go ahead!! I am still sitting educate their staff I am disgusted at the lack ofwith the same issue unable to receive calls . I missed an urgent call from Charlotte Maxeke hospital confirming my follow up after having completed chemo and radiation resulting in my date being further pushed back to after the 30 June!!! I am angry because every day when I go out it is a risk to my health!! I already have other illnesses that make me a target for this current epidemic!! Does MTN not educate their staff!!! I am disgusted at the lack of service yet every month I pay for a contract for a phone I cannot use!!!! Disgusting!!! I demand a new phone.
