Food Panda — foodpanda account blocked

From few days I am trying to access to foodpanda website I tried using different promo codes but it showing me that your account has been banned

So may I know what is the reason why my account has been banned by the website if they do not want to provide the promotion codes to apply the office then why do they send me an SMS regarding the promotion of first to be used to reduce the amount for ordering the Food

I request the consumer department look into this matter and I feel that I am not only the single person who is facing this issue but they many people were facing this issue I request you to please look into the matter and resolve the issue as soon as possible and stringent action to be taken regarding this issue for fooling people and for no reason banning the users account.
