WRONGLY DEDUCTING MONEY

I sent a letter of cancellation to SEESA on 09/10/2019. It was confirmed by Mr Abner Kubayi that the service will be cancelled on 31/01/2020. I noticed that a premium was still going off in March and contacted Mr Kubayi again. He referred me to Phillip van der Merwe who claims that he got a telephonic instruction from our company owner not to cancel the subscription. This is absolute nonsense. We would not have stayed on with SEESA as we did not receive any service from them. I have requested Mr van der Merwe on numerous occasions to send me written confirmation where we requested to continue our subscription. I haven't received any feedback as yet. I would like a refund as from 31/01/2020.
