MTN BAD SERVICE ONCE AGAIN

I just want to know what has happened with CUSTOMER SERVICE?? Well MTN has done it again. Why is there always problems and they never get back to a person. I do my dads business always have. My dad wrote a letter had to have it signed under oath and then copies of our ID which was emailed to MTN so i can have authorization on his account. Went well for a while for me to phone in and say sorry that no longer exists, but the actual complaint, We have 3, yes 3 contracts with MTN. The 15/01/2025 I what's app a lady from the Baywest MTN to confirm everything is in place for the 08/02/2025 as that is what the MTN app said and the *141* number you dial. I have all the messages. She said all in order but if i upgrade that day 15/01/2025 I would have to pay in R1900. Said no thank you i will wait till 08/02/2025. I confirmed the devises we wanted she said she will keep them, etc. The 08/02/2025, Saturday morning we go all the way from Uitenhage to PE to upgrade. She changes the banking details as i have been paying MTN for over 10 years via EFT, never been a problem. Now all of a sudden has to be a debit order, which I hate as they never take the correct amount off, always more, but we changed it. Gave his ID everything all was changed. To when it came to the upgrade on now I must pay in R2400 and all of a sudden our upgrade date changed to the 11/02/2025. I said what you mean. I confirmed everything with you before we came though, you confirmed all is in order for 08/02/2025 and that I will not be paying in. Now we get another sign song. No she will take it up with head office and get back to me on Monday. Waste my time and petrol all the way to PE for NOTHING!!! Monday she did not get back to me, I had to get in touch with her. No, she is waiting for head office. She said I can get my phone on Tuesday. Tuesday comes, still nothing. So I sent her another message. Oh, sorry she is off, she gave it to someone else to sort out. So I phoned Baywest branch no one knew about it. So I told the lady the story she checked on the system no I still need to pay in. No on can answer me why I must pay in. As all the years MTN can check, we have always upgraded 3 or 4 months before the actual contract expired and never ever had to pay in. So the Wednesday she sent me a message she got back from head office I can only upgrade once the contract expires. Then my dad phoned MTN. This woman says I can upgrade in March and I will defiantly not pay in. What the hell is the story. I have sent emails and no response. Why must I pay in now and I never have. The app and my phone says I can upgrade and nothing about paying in. Why must the customer always come short and always accept things and all you get is sorry from them, this is *******. All I want is my new phone without paying as as this is what the app and my phone says, not one person can give a person a proper answer or sorry I will make a plan or get back to a person. Been with MTN for over 10 years, maybe a time for a change. I have friends with Vodacom and I never ever hear them moan. What upsets me the most is everything was confirmed and checked before we went in to fetch the devices to stand there like an idiot and everyone looks at a person to say sorry you need to pay. Do you really think if i knew I had to pay I would waste my time and especially my petrol to make an idiot of myself. Really MTN. Do you think I am going to do that. Hell NO!!!!!!!
