Very very Bad service from MTN Vangate Mall

I am very upset with the way how MTN Vangate Mall assist their clients it's ridiculous that I as a customer have to wait 4months on my own phone thats finished paid for to be repaired within the time of its warranty I sent my phone in last year 7th December 2018 and came back on 26 January 2019 when it came back the phones speaker was way softer than it originally was the the consultant Shaun told me I have 24 hours to return the phone if I find any problems with the phone after it being repaired and immediately I rebooked the phone without leaving the store with Shireen and I asked her what would happen with my phone now that it's still not fixed and what will happen with the warranty because the phone came back after the warranty has fallen she told me she doesn't know and that she will have to speak to her manager regarding that but never got back to me after that I've been waiting from 26 January 2019 till now for my phone 2months passed I recieved no feedback from MTN regarding my phone I tried phoning MTN Vangate Mall several times on the number that's given on the internet but the phone just rings until it reaches voice mail I finally went back in to the store 31 March 2019 was helped by Mikhail to fined out that my phone was laying in the safe for the pass 3 months and never been booked it I was ****ed and mikhail gave me his personal number telling me to remind him to rebook the phone on Monday after helping me with my phone eventualy I messaged him 2 weeks after being in the store and yet I still didn't not recieve my phone at all I am still waiting it coasting my alot of money to travel from tokai up to vangate everytime for my own phone thats not being fixed I am very angry with the way MTN deals with their clients
