Dishonest Company

I cancelled my account with them more than a year ago because of poor service. Suddenly on 6 September they started debiting my bank account again: first with R 50.00, second with R 25.00 and third with R 125.00. These different amounts show deliberate intent to commit *****. They have ducked and dived my phone calls and emails: they are clearly dishonest: do not go near them!!
