Telkom “****”

This “****” doesn’t even deserve a star. I’ve been trying to cancel this contract but they’ve refused, this is my 2nd complaint.I been to the branch and they gave me an email address? I’ve emailed and they responded once and never again ? Now they’ve handed over the problem to debt collectors who’s threatening me, I’m not scared and I’m not going to pay them one cent! Until I get a response
