hi I am new to the forum.
Saw a new 2019 MacBook Pro 15 for sale on Currys eBay store for £1808 which was below usual selling price (apple RRP £2349). Ebay was running a promotion that weekend which gave me another £100 off with code. bought and paid with credit card. received order confirmation, invoice and despatch info all showing correct details.
however I received a 2019 MacBook Pro 13 (RRP £1949) 2 days later which wasn’t what I paid for.
With all respect to citizens advice, for this kind of thing the best one can say is that they are well-intentioned. I don't have much comment to make about Resolver except that they really not sufficiently businesslike about these things.
You haven't said when this happened but I gather that it happened some time ago and of course the longer these things are allowed to go on, the less control you have, the more comfort the other side takes and the more tired of it or you become.
