Can't cancel account, won't stop billing don't use the app, go no response from support.

Hi I have note used the app now do I want to use the app, I have tried to cancel the account which won't cancel, and am being billed daily which I have not authorised. I have now sent 15 emails to sales and support and have had no response. How do I cancel and delete my account, as we don't use this software and have no need to use, and how do I stop being billed for this software. Seems support and sales just constantly ignore my requests.

try to stop them by ur side like disabling credit card or other payment methods from ur side.

also try to self host it instead if u want to test or develop?
