I am being charged for a pro account for 2 months... But my account still appears as a basic one

Hi,

The title sums it up... I've been charged 3 times for a "pro" account (and I have invoices for each payment) and yet my account is a basic one : my meetings ends after 40 mins and can't open a ticket (meaning : I have absolutely no possibility of contact to any customer service). To be fair : I open 2 tickets but they are not being taken into consideration (no one replies nor reads them).

Really not happy (obviously) and wondering about the legality of all this... So I try here to see if I can get some attention
