Telkom ADSL Woes

I have had it with this poor service.My first issue i had with my line i had to resolve myself by going to the exchange.<br> Now that my line is working i have found out that i am getting a 2meg service instead of the 4 meg i opted for when i ordered the line.<br> Monday i phoned your sales and then upgraded to 4meg. The person told me 48 hours. It is friday today.I have been phoning since yesterday and people are just transfering me and putting me on hold.One women told me now i must pay 700 as it shows on her system.I PAID the R700 before installation already have the slip to prove it.Can someone just upgrade the dam line to 4meg please.I have spent 7 hours on the phone waiting just yesterday and today. Please do no respond with a ref no and with a message that technical or sales will sort this out. I have spoken to this imcompetent and clueless people numerous time since yesterday and keep on hearing a different story. Just respond on this mail and tell me my 4meg is up and running because it was process on monday already.R700 FOR installation has been paid.What else do you want to get this going.I am so tired and frustrated at this moment.My landline number again is ***.
