Bad aftersales service

Such poor aftersales service. Telkom came out to do installation, within in 2 hours both landline and internet was down. Called DSL and sent email. No response via email, was told over the phone they only do sales and that i need phone Telkom to sort it out. Such bad service from these people still waiting on this to be sorted. Have heard nothing from DSL. When it came to signing me up i was pestered everyday with a phone call and email.
