Ended up with a unit I did not book! Flexiclub treats me like an imbecile!

Made a booking for a SUPERIOR sea view unit at La Montagne in March 2021 and downloaded my guest certificate indicating as much. NOW I'm told I only have a sea view unit. They are ignoring the fact that I have PROOF that I booked a SUPERIOR sea view unit. Will also not let me speak to CEO, Shaun Lamont. Wonder why? NO response to emails sent to them. WARNING: Take a screenshot of every action on their website as they cannot be trusted. I paid extra for the superior unit, but am now stuck with a standard unit. Instead of investigating my complaint, they sent me a copy of the booking as reflected on their system. Will not take responsibility for the fact that THEY *****ed up when they populated the system with the resort details. Manipulative conduct!
