Is there ANYONE who can help me??

I used to receive daily notification emails indicating my data usage. They stopped without me requesting this. I am also unable to login to the usage tracker (system doesnt pick up my username at all for the past 2 months of trying). I have contacted Telkom via chat, email and telephonically (put through to 6 different people). They just keep saying that their system is down and they're working on it. There is no way for me to know what my status is on data usage.<br> A year ago a Telkom sales lady phoned me, selling me my current 2 year contract telephonically. This included 100GB per month. I have never been able to use this much per month, but this month I've reached my cap only half way through the month. It seems the sales person failed to mention that 50GB of this deal was only valid for 1 year and that the remaining year I would have to make do with only 50% of the promised data! I gathered this much from researching expired deals online, but dont know for sure, since no-one can advise me, nor can i access my data allowance/usage at all.<br> Can someone PLEASE assist me?? I really dont know who to contact, since Ive tried every avenue.
