Very bad service and attitudes

I hope you can help me ASAP I live in George, Western Cape. I work for a international company called TutorABC. My job is online teaching! I went into telkom to buy data for my ****le and an agent recommended a router you have on special at the moment and promised me it is better for the work I do! The router is not good for what I do and I can not work anymore! I have lost R5000 in a week because of **** service I got from telkom. I have logged a fault on my pings on the router and no one responded to me yet and that was 4 days ago. So I went to telkom again and got the R699 10MG line and they tell me that it can only be installed on the 06/10/2015. I don't think any one understands this is my work and because of the unbelievably **** service I got from telkom in george and the call center I can not work and I earn money as I work IF I DON'T WORK I DON'T GET PAYED! I need my line installed this week!!! I am really very upset with TELKOM and the service I get from the staff.
