Budget Catering

I enquired yesterday , obtained a menu hadn’t even had a chance to really look at it and or check dietary requirements , approx numbers before i could really look at the offering.. I recieved an email less than 24hrs later in capital letters “ CAN YOU PLEASE LET US KNOW “ and a date has been blocked out ?Thank you but no thank you. Where is the email etiquette ? And as i am clearly being pushed to commit ? I will not be giving my business to Budget Catering to which i replied advising so and the response was even more dreadful and what seemed like an internal email ( not addressed to me or anyone ) it reads“ rejected client, not our profile remove and ban with the association, please so other members won't have issues “As a individual with sales experience and overall business professionalism this is really poor form , poor follow up and not how you obtain a client.
