Appalling service from Vodacom Internet service

For more than two months access to Bills and Account details on line have been unavailable! They are having service problems. We download Cellphone bills for submission to claim expenses monthly - not available (sorry we are having a problem). Tried twice this weekend to desperately get the call centre to download and send same to my email address - sorry not available yet! What are we supposed to do? Wait another month was the response from Customer Care!!! What has gone so wrong that Vodacom cannot fix its own Internet problems and ****** the customers - nobody interested in helping at all. What are we as customers supposed to do - locked into contracts? Who is interested enough to even bother helping resolve these issues? Any suggestions?
