Worst service ever experianced!!!

Vodacom has been extreamly unhelpful over the last week. Earlier this week i recharged my wifi number with 500MB data. Later that same night (2:15am as seen on the vodacom system at a vodashop) the data was consumed. 450MB in one go. To ad insult, the data on my new phone contract also just vanished! Vodacom then went and started charging me out of bundle rates! R1 something PER MB!!!!! in the space of 10 min my account shot up by R150!!! Then when I tried to log into the vodacom site to see whats going on with my account (STILL being charged even when using the FREE vodacom site!) but the website wont load and the IT guys have been working on it all the time since the start of the week. RIDICULESS!!! BUT yet I must pay for things I did not use and NOT ONE person at vodacom can help me. Whats the point of a customer sevice dept when there is no customer service! Even more ridiculess is that I have prinouts of my account 5 min apart where my acount is still charged out of bundle rates even after I reloaded MORE data on my number! Even the manager at the vodashop said there is something serious wrong but vodacom will not even help when a vodashop calls. Then I call vodacom to get a quote from them to move over to Cell C on a buy out contract. The first call I made the consultant told me that the buy out will be R10 200. So sad that it was not mailed to me. When I called again for the same quote, the amout shot up to R11 600. Now I ask you where do you get you numbers from? How can you charge people these amounts of money and then treat customers like we owe you something for using your service! Im a customer but Vodacom has no idea what customer service is! As im writing this now im waiting for a consultant on the phone. And no shock here, again I cant be helped. I must tell you that I have never felt so insulted in my life. I dont even want to go into what just happened on the phone!!! The data billing query will only be completed next month the guy said. AFTER vodacom has taken the money from my account on the 31st of May. SORRY VODACOM! I WILL NOT PAY THIS. I WILL NOT ALLOW YOU TO TAKE ADVANTAGE OF ME ANY LONGER! IF YOU TAKE A CENT MORE THAN WHAT MY BILL SHOULD BE, I WILL REVERSE THAT DEBIT AND YOU CAN TAKE THIS NEW PHONE, THE DATA CONTRACT AND MY IPAD DATA CONTRACT AND YOU CAN STICK IT WHERE THE SUN DOES NOT SHINE!!!!!! This is the worst company I have ever had to deal with and I will make sure that every person i come into contact with hears about this. Loyal customer treated like a fool, talked down to like I dont know what Im doing and the told by customer sevice to not be upset when my bank account is about to get ****d!
