MTN does not value their customers

I would like to express my disappointment in the poor service that i have recieved from MTN and it's agents. For the the past four months i have been going back and forth trying to do a swim swap with no luck. Firstly, during the level 5 of the lockdown i could not speak to an agent, understandably so, however the sms option that i had to use was ridiculous and it resulted in my number being blocked. Secondly, when trying to query this,i literally had to make contact on their facebook page,the call centre and send numerous emails before they could even respond to me and when they did respond it was a prompt response, basically every different question i had, had the same prompt response on facebook and on email it was question after question. Thirdly, they had me do an affidavit stating that i was the rightful owner of the sim card/number, only to have them "block" the number, meaning it has now been recycled and i can not get it back. What frustrates me the most is the fact that no one at mtn is taking accountability as to why the swim swap was not done on time and nor prove to whoever the big boss is that i have tried numerous times to get the number within the stipulated 3 months, wherein they took 2/3 weeks to even respond to me. It was very important that i get that number because it is connected to most of my accounts, school(which by the way, i haven't been able to do because i still haven't been assisted) and other things.Furthermore, it means that i have wasted energy, time, money and resources all for nothing, even after being a loyal mtn customer for so many years. Oh and by the way,i had to stop at an MTN store to find out that the number has been recycled because i am still waiting for a response.
