Not able to provide services paid for and not refund

We requested a quotation and paid for the folders, t-shirts and pens from this company.

They (Michelle Rowe, the director of the company) then sent us samples of what our logo would look like on the various items.

These samples were far from what our logo look like and only when we told her that we not happy to sign off for her to continue with the work, did she start talking about the fact that:

- the metal piece on the folder only allows for one colour - her quotation only provided for 1 colour to be put on the items; however, at no point before we told her to refund us, did she raise this issue.

She then agreed to refund us and we then send her our bank account details yesterday- to date we have not received any response from her or her company acknowledging the receipt of this email. This is totally in contrast with her almost immediate responses to our emails up to before we asked her to refund us.
