I bought an item from Machine Mart (magnifier & Fl light) it was useless, quality of magnifier lens was so poor everything was out of focus.
Took it back the next day ... as I had 'opened the box' would only give Credit Note.
Next time I went to buy took Credit note to pay (>£50 credit) ... to be told credit note expired. In the very small print there was a date limit ... certainly not mentioned by the shop at the time.
I took it to customer services - who also said 'No' ...........OK I asked could I have the original item back then, at least I could sell it .......... to be told 'No'
Fells like I have been robbed ... they have my money I have no goods.
So be warned if they offer you a credit note.
