Cut my business telephone line without authorisati

On 5/08 my business telephone line was disconnected, so no card machine, telephone, fax, internet or wifi in my boutique. Upon investigation, it was found another business owner requested his line to be disconnected, but made a mistake with the number. So Telkom obviously does not check to see if the instruction matches the owner of the service and since raising this matter with them have only received bad attitude and an inability to understand that they made a mistake, claiming procedure WAS followed. I had to re-apply and complete the forms again for the service and then, after a week and 3 days of no telephone, I received a new telephone number - right after I had a 1000 business cards printed. To have the number changed back to the old number, I had to write another letter, with my name and ID number - who knows why, because it is not procedure to check it according to the Telkom!! The total lack of acknowledgement from Telkom side makes me believe that this will happen again and again, because they fail to see how it is their fault?
