Poor Service - Sales / Service / Accounts

I have ordered a landline move to a new location and (new) ADSL. Waited 2 months. I cancelled ADSL. Telkom never cancelled but installed ADSL that very same week I have posted a complained on Hello Peter. After installation internet never worked. After numerous calles and emails I requested ADSL to be cancelled and equipment to be collected. Never happened. Yet I was invoiced for two months ADSL. I requested ADSL charges to be reversed. Still not done! WHAT TO DO?!
