Congested exchange for 4 months?

4 months ago we logged a fault to telkom due to a congested exchange (welgemoed)<br> Technician came to our house and admit the exchange is congested but nothing can be done and we must wait for other subscribers to abandon their service for ours to be better. (***)<br> We created countless fault reports after that via web and phone but either they just close the fault or nothing comes of it. Sunday one of their technicians finally showed up and made promises of trying to switch us to another port at the exchange but nothing happened. (***).<br> This morning i created yet another fault (***).<br> <br> We are unable to use our internet after 5pm every weekday and all weekend long for this 4 month period now.<br> <br> CAN YOU PLEASE DO SOMETHING ABOUT YOUR CONGESTED EXCHANGE??
