MTN frustrating IVR

Does a MTN still have a functioning call center? Why is it so difficult to speak to an actual human being? I am getting frustrated listening to the IVR. Tell me why would I call 135 to enquire about my balances? I think everyone knows how to check balances using the USSD. But instead of MTN having an actual call center, they have an IVR which tells me how much I have in my account. What a terrible service.

All I want is to speak to someone who can assist me unlock my MoMo account. Even the option 5 on 135, does not give me an option to talk to a person. It's all useless staff on how to use MoMo. I mean, in this day and age? Why would we call call center for such things? The WhatsApp line also does not have an option to speak to an agent. It's so frustrating. Is this even legal?
