Data, email and useless customer services

Vodacom services is really getting worse by the day. At first some phone number's data could not be used. We tried to phone their customer services but after holding on for almost 24 minutes we were cut of. When we tried to phone again, their phones didn't even ring. The next day everything was fine again just for other numbers to get the same treatment. Now suddenly last night when my husband wanted to check his emails on his phone, he got messages that his password has changed, He didn't do it and as he is home all day, nobody has access to his phone to change it. He can't even access it through Google. When he phoned Vodacom, they couldn't tell him why it is happening and told him to change it through Google and Vodacom.co.za. We did that but he still can't access it. He even sent "forgot password and received a new password. He waited 40 minutes and tried that password as well as the new one and old one but NOTHING works. So when we phoned customer care again, they told us after almost 19 minutes on the phone that they will have to escalate it to technical services and they should resolve it within 48 hours!!!! Why do they even have people at customer services if those people doesn't even know how to help you or how to resolve your problem?
