Shocking service

Absolutely shocking service just to get an upgrade done Trying to upgrade for two weeks have all my information required to do the upgrade but don’t respond to my emails and I’ve been put through from one number and agent to the next with no help Easy just to keep passing me over and we have been with Mtn for years Worst experience ever My battery was on 100 when I started the enquiry again today o am now on 14 percent and still getting passed Don’t need this bad service I’m moving to vodacom
