Most shocking service ever Vodacom!!!

Once again - I sit with the same problem not even a year down the line!!! Almost a year ago I had data queries on my account, it took Vodacom forever to get it sorted out but eventually they passed a credit and everything went fine for a while - my data didn't just disappear. Now in 2 days their call centre once again treat me like an idiot to try and convince me that I have used 25GB of data - Really do I have to go through this once a year. And so much so for being a RED client - they want to log a call and I have to wait for 7 Days - totally unacceptable!!! - I have a business to run and don't have time - needless to say I wouldn't want to know how they treat the rest of their clients. The manager totally refuses to speak to me and the call centre agent refuses to give me her surname - SHOCKING
