Lack of assistance from Flexi Club to rectify website and app access issues.

I have been a member of Flexi Club for well over 20 years and our family has enjoyed some wonderful holidays through them. However, recently I have been unable to access their website or app to make reservation enquiries and I keep getting the message that my login details are incorrect. I have tried resetting my password, but never receive the link to be able to do so. I have emailed and spoken to various people via email and on the telephone about this problem. Unfortunately, the people I have spoken to are just trying to get me to make a reservation, promising to get someone from IT or related to contact me - something that never happens! This has been ongoing for at last the last four months and I am no closer to gaining access to my profile on the Flexi Club website or app. I DO NOT WANT SOMEBODY PHONING ME AND TRYING TO SELL ME A RESERVATION - I WANT THE PRIVILEGE OF BROWSING WHAT IS AVAILABLE AND MAKING MY OWN BOOKING!! Poor show, Flexi Club!! :(
