Don't ask for internet speed upgrade

Telkom, why is it that when I place an order with you to upgrade my adsl internet speed from 2 meg to 10 meg, that you switch off my internet COMPLETELY within an hour of placing the order, then leave it off for 3 days, and counting because I am still waiting for internet to come back. I tried this in December and had no internet and also not telephone for 3 weeks over the Christmas period. Why send out technicians who do not know what they are doing. My reference number is 795CRK300615. Could a miracle please occur and have your technician please return my internet service. Why do you not just leave me with my 2 meg speed until you can supply the 10 meg, why switch off the whole internet for days and weeks within an hour of placing my order. Sick and tired of Telkom.
