Useless service provider with major problems

Vodacom is really so absolutely USELESS lately. You had data problems TWICE recently and since then we can't get our emails on our computers or tablets. I phoned the call center this morning and got through after a long time, then while explaining to the person what is the problem I was cut off. I phoned again and after 15 minutes got a repeating message about them being very busy and to phone back again. Then they sent me few sms's that stated that they tried to phone me!!! They LIE because I was right next to their own installed signal booster and my phone didn't ring once. Needless to say the problem is still not sorted and I've been holding on for a consultant now already for almost 8 minutes after phoning 3 times already. It is now after 4 and they still have high call volumes which means they have major problems.
