Can't complain about service because there is none

Mtn has got to be one of the places with the WORST customer service in the WORLD, and I mean from customer care right up to head office, there is no service at any department. I have been struggling to get my number back since November last year when they disconnected/ recycled (whatever they call it) and relocated it to someone else all this while my number has been active, but according to them it was inactive for 3months. Since then I have been to the MTN store 3times where I could not be assisted because the number has been given to someone else, all they suggested is for me to contact the person using the number and ask them to give me my number back, which I did and the person could not even understand English so that was a failed attempt.

Yesterday I tried calling the number to see if it's still active to my surprise it wasn't, so I called MTN to find out what's going on with the number, they told me it has been disconnected and that they would have to put in a request to activate it again and I need to wait 24hours for it to be active and then I can perform a sim swap. So as told to I called in this morning to do the SIM swap ( needless to say I obviously didn't pass the security questions) because I last had access to my number back in october before they gave it to someone else, so how the hell am I supposed to know the last method used to recharge or the amount recharged. Then when is called 135 and selected option 1 which is "calling regarding a number other then the one your calling from" it said that the number is Rica barred, now I don't know what that means so I called the Rica department directly who told me that I would not be able to do a sim swap because I don't have the SIM card to Rica it, now how the hell am I supposed to have a SIM card that was given to another person, and how is it possible that if your SIM is lost/damaged or ****** for them to assist with a sim swap but they can not assist me because I don't have the SIM card.

Since last night I've spoken to 5 different agents on WhatsApp, customer care and the Rica department every single one with their own explanation, not one of them even closely similar.

They don't even have a clue of what their own terms and conditions says, and forget getting in touch with their head office to lay a complaint, their line has been busy 6months now, that's how long I have been struggling with this.

They clearly state in their terms and conditions that if your number has been disconnected/ recycled and not given to someone else that you can get your number back, so I understand that it has been given to someone in November but that person clearly wasn't using the number anymore because it was disconnected/recycled again, so nobody is using it now so why the hell can't I get my number that belonged to me in the first place which is linked to my bank account, and a lot of other accounts. Or are you waiting to give it to one of your friends to commit *****, this is ridiculous.
