Vodacom - Yet another complaint and terrible customer service!!!!!!!

I don't know how many times I have been dissatisfied with Vodacom over the last four years. All that I do know is that I will never renew my contract with them again. After not being able to access the Vodacom website to view account balances for a year now, and after requesting relentlessly that they rectify this, I have resorted to phoning in which has proved to be an equal nightmare. I phoned in on 11 May and requested 250meg once-off data. Instead, I have just checked my data balance and realised that the dear competent consultant had loaded a 2G once-off data bundle. How absolutely frustrating it is to be a loyal Vodacom customer!!!! Fix this Vodacom!
