Telkom = useless

I cancelled my contract with them 3 months ago and I am still getting invoices, including interest on late payment. The most useless company ever. Do they only hire idiots? There side-show OpenServe then had to install fibre to my office. Could'nt get it done in 5 days. Only excuses and no shows! Vumatel did it in two hours at another property of mine. I rest my case.
