Poor experience for first time buyer!

Ordered Online 2 X Phyto Pro product. Purchase and payment acknowledged and told "We have just received your order and are happily packing everything you asked for. " Four days later receive e-mail stating they cannot fill the order as out of stock and given three choices - I ask for them to contact me. Nothing! I call them and first call dropped, then put through to 'Online' which just rang and rang, no answer. Pathetic. 1) Why does your website not state stock holding or out of stock (this is the 21st Century) - far smaller operations manage this. 2) Do no lie to me that you "are happily packing everything you asked for" when in fact you do not have it! 3) Do not take my money and then not communicate effectively. 4) Contact me as your e-mail option states.
