VERY UNHAPPY TELKOM CUSTOMER!!!

I ordered the special uncapped LTE R899 package from telkom in July. We were told wrong information about this package and therefore phoned Telkom to cancel as they give 7 days cooling off period where you can cancel. Which we did!!!! We were told that we will receive a phone call to arrange collection. I phoned Telkom today 16th August as they have taken money out my account for a service I am not using. I have told them to go back on the recordings and check when we phoned to cancel. They never canceled when we phoned during the cooling off period and now I will lose my money!!!! I am very unhappy and want to take this further. They need to find people who are able to do their jobs and not be so ***********.
