*********** call center

I have been a Superflex customer since July 2024. Received my data, unlimited calls and SMS every month until the 27th April 2025. They debited my account on the 27th April 2025 received my data and SMS but I cud no longer make calls. When I make a call the robot tells me " I have insufficient airtime to make calls" when I'm supposed to have unlimited voice calls. I have been phoning the call centre several times everyday for the past 8 days for feedback. The feedback on my reference number is always the same, can you please ask the client for his number and the problem his having. How do you give a customer who calls several times a day the same feedback everytime. Today is Tuesday the 6th of May 2025. MTN still wants to know what's my number and what is my problem. *********** ppl in that call centre. Try to escalate it you get voicemail at the supervisor desk.
