Contract Cancellation just a MESS with no assist

I have never experienced such awful service. The Fourways Mall MTN branch refers me to Call Centre to cancel contracts because they are a "Sales branch" which just said to me, after sales, we dont care about you anymore. Anyway i called the 083 135, everyone saw my details until i as referred to Cancellation team, the guy assisting me (Sello i think) verifies me then tells me to hold, he then starts chatting with colleagues/friends on the side about taxi fares, people being raided for R10 etc (i think i was supposed to be on hold/mute) then when i say "Hello" to alert him that i am still on the line, he comes back with a "system offline" and i must call tomorrow. Kanti how difficult is it to cancel contract? Seeing on other reviews, it seems MTN contract cancellation is just a mess and everyone has to go through this route to be listened to. Contract ended 02/06/2021 (info provided by call centre) on cellphone number *** but you would swear i still owe millions. People need to us as clients seriously and value our time, holding the phone for more than 20mins before being helped then get such awful service is not ideal for any sales and service related business
