MTN BAD SERVICE

I was ****med by a MTN staff member who knew all my details even my debit order acc no. They took my airtime. I phoned ***** dept. What they did is unknown. This was more or less Sept 2023. Since then my phone is not registered on the MTN network. I have a 3 yr contract and paying for the phone. I phoned several times. On the 21st of May they gave me a ref no and escalate the call. Said it will work after 5 days. Nothing happened. Ref no REQ***.. on 1st of June the escalated to support team with ref SMC***...I need Auth to collect a new Samsung Galaxy A32 as nobody seems to know what happened and cannot register the phone on the network. I paid for the phone which they blocked. Please do not support MTN. My cell no ***
