Telkom Strikes again

Hi all i have a wireless router and 10gb data contract with telkom! data goes out of bundle and i phone them to add another 5 gig. started using it for 2 days and it is finished again? phoned them they say they can see we only used one gig and the rest is gone and they will open a case. then after we urgently need internet get another 1 gig yesterday cause the case takes 72 hours it also disappears. one person tells me they can see my case and the other says nothing was logged!!! then I phone again, after talking more than a hour the team leader dumps the phone in my ear not solving anything!! the people are so UNhelpful its ridiculous!! after sending me reports of me using it at like exactly 00:01:00 every morning. they still cant give me proof that it has been loaded on to my account but i get blamed for using it up. they have no proof and all of them just keep on saying they are sorry they cant help me. my Fiance needs the internet to work from home and she is losing money every minute this goes on!! maybe suing them for loss of income will wake them up !!! and the best is i will probably end up paying for something i did not get !! well then it will be HELLO CONSUMER ACT !!
