********* sales practices

This company just lodged a debit order on my account without my consent. 2 debit orders of R285.00 has already been deducted. My bank can't stop it. Said I must contact the company to stop it from their side. I did that today. was promised that within 24 hrs I would be notified that the debit order is cancelled. I wait! My frustration is that I never signed up for any product. They say I did by swiping on one of their devices and inserting my pin. I never did this, but they adamant that I did. I suspect that some ********* sales people operating in the malls are using ********* means to register you on their devices.
