Terrible service from *********** staff

We have Telkom Internet at our home in a gated community in the Strand. I needed a higher speed internet and upgraded my service for 4 months. When we left to go to the farm again I tried to contact Telkom to down grade my internet to lowest service package as no one was needing it. I was send from the one agent to the other numerous times over a period of one year. Eventually one day I got the energy to try again I landed at a agent who without hesitating told dme what to do. I completed the forms and submitted all they needed and nothing happened I got the same account in the following moth I contacted them again and they said I must fill in a debit authorisation form which I refused because for years I paid via Eft. I asked them them to terminate my service with immediate effect and again I had to fill in documentation to send to them. I did not hear anything but I recieved a threatening letter from a attorney for account payment in arears. Terrible terrible service after I paid the full amount for the upgraded service without using it for a year.
