Vodacom Server Slow/Not working

Every time I try to log on to the Vodacom website it takes approximately 3 minnutes to find the server if it is found at all. Due to this I am not able to see my invoice or other things pertaining to my account.<br> <br> I also do not receive my account at all if I do not log on to the website, despite numerous calls to the call center to send me my bill via e-mail on a monthly basis. I am therefore forced to phone the call center every month so that my bill is sent to me. I have also been over charged for data which Vodacom is unable to resolve.<br> <br>
