pathetic service

I am still waiting for feedback regarding call 1917CRK270115. i have been visited by a telkom gentleman for an upgrade however i have no internet ever since. i have been billed for the entire month of Jan where i have had no service. can someone help a paying customer urgently!!!!<br> i want the name of the individual that did my upgrade and advised that i have VDSL when this clearly does not work. telkom advised that they will resolve within 2days? when i logged this early last week!
