Poor Service

I took a phone Contract with the MTN they never debited to my account its been three months now I tried to call them on December 2020 they said my number its on migration can i phone them tomorrow. I phoned them they did not pick the phone this today I email them and Jabulile Myeni reply back saying that your account is with our Legal Collections Department, so please call 135 and ask to be transferred to them. I did that five times instead they make me hold more than 30 minutes. They have my number but they never call me about my account. Instead they called my manager and ask for my phone number.
