Update - 9 Aug 2017
After being contacted by Ebuyer Customer Services who listened to my concerns, I have been provided with a full refund.
I am putting my previous experience down as a misunderstanding which has been satisfactorily dealt with in a pleasant and caring manner.
The 3 stars is because this whole episode has cost me 2 lots of postage and inconvenience with no additional compensation to acknowledge this.
I would trade with this company in the future, but with more care.

Bought a TP-LINK TL-PA7010P KIT AV1000 Gigabit Passthrough Powerline Starter Kit from them.
On delivery, found it didn't work. Went through trouble and expense of returning it for a refund, only to be told they don't accept returns from Business Accounts. They are sending the dam thing back to me apparently! Pointless! FIND A MORE CARING PROVIDER IS MY ADVICE.
