Useless Service

We have a business account with Vodacom for 3G as well as our cell phone lines. I logged on to the Vodacom website and noticed an sms had been sent to the data number (How I am supposed to get numbers on a 3G ****le I would love to know?) and the account had run out of data. I then attempt to buy data on the website. What an absolute joke. The website takes you through the process (that they call simple) and when you get to the end it says you are not the master account holder and cannot purchase data. Now my account has gone over the limit by R 600,00 so I call the call centre for assistance. I speak to someone who says I must hold and passes me on to someone else where I have to start from the beginning. Speak to someone else and he is unable to assist. Third person I speak to says I need to send a signed letterhead and ID copy of the owner of the account (who is away so this is now impossible) and then hangs up on me when I tell her its a ridiculous solution to a simple problem. I phoned back to speak to a manager and 2 hours later I am still waiting for a call as my account gets higher- I demand disciplinary action against these employees and a refund for all data used today!!
