No where to be found, no response no nothing

Our company received an email from above company on promotional gifts. We enquired about the sweet tins and they were very quick to respond. They were also very quick with our branding and we placed an order. Well, I have followed up in October - still got a response to say it will be processed in November. November came, been told that I must refer to T&C's as it is a very busy time (although we have placed our order AND PAID!) in July already. Now, there is just no reply to any emails, phones seems out of order as no one can get through to them and no response to my request to cancel our order. Who else had the experience with this company? Please be aware!
