Onepet Cancellation and debit order Frustration.

I decided to get Pet insurance on my puppy so I requested a quote and said I want to first speak with my partner and go through the paperwork first. So 3 days later I try to get in contact with them and speak to an agent on the website chat portal. They said all I need to do is send an email. They did not say that after the email I will be called and requested to confirm over the phone. They tried to call and email 5 days after the email for cancellation was sent. Now on Friday i get sms and email welcome and your debit order will be going off. I work at a job whereI do not have access to my email or calls. When I called today they said nothing can be done about the debit order it has already been requested. And they can't do anything about the bank charges that will happen because there will not be the amount in my bank. Cancellation can only assist on Monday after their mess up. This is really poor service.
