MTN - NOT RECEIVING WHAT I AM PAYING FOR

I have been a loyal client of MTN for the past 16 years. Evenn though I was offered lucrative contracts with other service providers I opted to stay with MTN however I must STRESS THAT SERVICE LEVELS OF MTN HAS SERIOUSLY SPIRALED DOWNWARDS over the past few years. I upgrated my contact on the 29/11/2019 for a black friday special (which ran for the weekend) where I was told I would recieve the following per month and my subscription would be R349 for the first 3 months and this would increase to R499 for the remainder of my contract: - 100 minutes anytime - 5000 minutes MTN To MTN calls - 25Gigs of data - 100 SMS This was fine up until 25/07. On the 27/7 I noticed I only recieved 100 anytime minutes, 1Gig of data and 100 sms. I called the MTN contact centre numerus times and given options but there was not option to speak to a consultant. I visted the MTN Westwood branch and the consultant logged a inquiry via her computer however I received no call from MTN. I then took it upon myself to visit the MTN branch I too my contract at, MTN Musgrave, and was instructed to bring in my original contact as they did not hve a copy and could not retreive it (MTN is a Muti Billion rand T/O company and does not have an online contract retrieval application ). A few days later I took in my contact only to question by the consultant if I had received a call from MTN to confirm my contarct of to downgraded it. I had just upgraded, how could I be down graded.

HELLOPETER, I would highly appreciate if you invetigate further and provide me with feedback as i am not getting any assistance from MTN Please can you investigate further as i signed for the Black Friday deal and now I am paying for contract and I am not receiving what i signed for. SHOCKING
