Bad customer service

I joined First Loyalty Plus beginning of Dec 2021, signed by a lady called Nereshni. At the end of Dec, I sent an email to the company email address to cancel as I no longer required the service. I also sent Nereshni a WhatsApp message to alert her of my cancellation. I did not receive any response on my email or WhatsApp message. My message was read (blue ticked) with no response.

In Jan 2022 there was no debit on my account and no communication from the company or Nereshnie. Then on 01 Feb, my account was debited. I sent an email, sent the lady a WhatsApp, still, nothing got blue ticked. I phoned the call center they said they will make sure the account is canceled but on 26 Feb my account was debited again. I am very disappointed that a company can enjoy taking people's money and not care like this. Every time when I send the lady a WhatsApp she just blue-ticks me but when she was cold calling me, she was forever calling me and told me how she works closely with her clients but after I signed up it was no longer the case. I had to go to the bank to stop these debits as they were not going to stop.
