Lemon Tree Hotel — lemon tree membership

I took the membership of lemon tree by giving around 8k bucks.
They have given me one night complimentary stay vocher for that and showed me other great benefits.
They are big time liars and cheaters.
Now for any date i am trying to avail that voucher these people say that hotel is not available for mentioned dates. I asked them to give me hotel booking for any weekend in next 4 months to which they again refused.
Same hotels are available through any travel portal for any of the mentioned dates.
So, in a nutshell my whole money is wasted in membership.

I am writing this review so that in future no one else would become culprit of their fraud membership programme.
