You are not User friendly I very frustrated with you

I battle no for 2 months to update my payment method I have been trying with no success to update my payment method. I try all my cards. The process goes as far as the approval of the transaction on my banking app and then, it redirects be back to the Showmax website, and this notification appears every time "saying there is a problem please try again" That is the end and I wait a few day and try again. This is very annoying. I cant find any place were I can log this beside Hallo Peter. Showmax you are not user friendly.
