If after reading some of the reviews you are starting to panic. DON'T.
I will tell you what I did to get a full refund(inc p&p) when I bought and recieved a memory module that didn't work for my laptop.
Under the distance selling regulations 2000 you have a 7 day cooling off period starting from when you recieve the item. Plenty of time to check it works and email the seller 'that under the distance selling regulations you are cancelling the contract and want a full refund'
(please note these regs only apply if you did a 'buy it now' transaction)
Like most people this seller is out to make money, so won't readily give you a full refund at the first time of asking.
Firstly you need to return the item. This will have to be at your own expense I'm afraid. He will insist that you return it to the USA, because thats where he lives, if you didn't already know. You don't, just send it to the return address in Birmingham using recorded delivery. If you have lost the envelope it is
Komputer Solutions Limited
210B The Big Peg, 2nd floor
120 Vyse Street
The Jewellery Quarter
TO EBAY:This address will be stated on the reverse of the package anyway.
I spoke to them just to double check it arrived and they came across as good guys. All they do is forward it on to fastmemoryman for you.
You will get an email from fastmemoryman about 10 days later saying that he has recieved the goods and that it has been tested and in working order. IMPORTANT please keep the tracking reference and the email confirming he has recieved the item. He will then issue you with a partial refund. This is where the fight begins.
I spent time on the computer sending emails asking him to honour his obligations and give me the remainder of my money but to no avail. So I eventually got fed up and left negative feedback(he will also give you neg feedback)
As I had payed through Paypal I went through their resolution centre. So after a few emails of getting no where I escalated it to a claim. Paypal will want confirmation that the item was returned to the seller before they pay out.
From cancelling the contract and returning the memory to getting a refund took about 2 months. So don't give up. Remember as a consumer you have rights.
He will also ask you to mutually withdraw the neg feedback. This could be used as a bargaining tool to get your money back quicker.
No matter what the seller says in his emails, if you have cancelled the contract within 7 days you are intitled to a full refund. Don't give up.
