poor customer service

MTN ignores my requests to fix a bug that hinders me from accessing my invoice online. I have to phone them every month so that they can send me an invoice. Every time I phone it's a whole process just to get an invoice. I've logged calls, send emails, asking them to please fix my online access but to no avail. Unfortunately their customer service is so bad, I've decided not to renew contracts with them. Best to avoid this company and save yourself many frustrations.
