epromo appears to be non-existant following a purchase at decorex

I purchased 2 x bamboo pillows at the recent Decorex show in Cape Town. I was assured that a full refund would be provided in the event that the pillows were not suitable. I sent an email to epromo saying that I am not satisfied and requested a refund. I got an email back from "Raymond" who provided more USP's with regards to the product but did not offer me refund. When I tried to email Raymond (no less than 12 times), I received an error message to say that the email address did not exist. I then tried to call their customer care number, which is also out of service!

I sincerely hope that there is a technical problem rather than a case of *****.
