Vodacom’s lack of customer service

So I did an upgrade with vodacom in January. Since the 7th of March 2018 when they forwarded me an incorrect invoice I started communicating with them. I spent hours with them over the phone, with + 30 service requests each month sent emails to all their departments and even drove to their shops more than five times but till this day I have not received any assistance. I have been making payments, requesting recordings that are never sent but to top it all my lines have been disconnected and they never listen nor respond all they are good for is sending smses saying your request has been resolved, if it is not your account is in arrears. Stressed, frustrated and inconvenienced in every way possible. I don’t know which is worse spending hrs on the phone or the *********** individuals that I am then subjected to dealing with.
