Mweb *** service

I am struggled for a week to buy my monthly R399 package but I was unable to. I contact you from my cellphone spend over R200 airtime without proper assistance. I cancelled my account and was told within 5 business hours I will receive an email that shows my line has been released. Still nothing. On Monday I requested to speak to a manager and no one has called me since. I am ****ed beyond words. I will not recommend your service to anyone. Can you please send the email to release my line.
