ADSL line Errors

I logged a fault on my line with my ISP, they logged the fault with Telkom, it has been four days and no one has yet to contact me regarding my issues. I have a 2mb/s ADSL line and my current sync rate is 512kb/s, my average download speed on SAIX is 0.18mb/s, this is unacceptable, I pay a lot of money for service but there just seems to be no care from telkoms' side, the customer is just not important enough for them. I want my line fixed. I have work to do and with this horrible service I am now four days behind. There has been 14 errors logged on my line. Please fix it or further actions will be taken.
