Special offers Scam you are not respecting timing you are lying

You post special offers and change the conditions without respecting what you announce. I saw an offer for around 50€ for 20 000 which was supposed to expire in one hour and 30 minutes. I logged off and 5 minutes logged on again and the offer was now of 79€ or so for the same amount of diamonds. Why don’t you respect what you announce. That’s what i call a scam, you are baiting and playing with players decision making, and lying in your offers. Or at least in the duration of the offers.

I don’t know if there are regulations about that kind of scam but i believe it’s disloyal and disrespectful.
