Greencell Avis 

We were surprised to discover that this isn't a British company as expected. None of the known UK phone numbers are functional, leaving us without a way to get in touch. Communication through seller platforms like eBay or Amazon is slow, often taking days, and it's clear they aren't based in the UK. We received a brand new battery that arrived badly damaged, and customer service seemed indifferent, taking their time to offer a return label. This meant we had to lug a 20kg battery to a UPS drop-off point, with no information on whether a replacement or refund would follow—or when it would happen. We're still waiting.

what a shock; we thought this was a british company however, all publicly known uk phone numbers do not work, no way to contact them and when you go through seller site (e.g. eBay or Amazon), they take days to respond and clearly not UK based. Bought a brand new batter which arrived in disgraceful damaged condition and without any customer care or focus, they took their time to simply say they'll send us a return label so we can take this 20kg battery UPS to drop-off point, no hint if they are sending replacement or refund...and when? still waiting

Being working with them for a wile now, so far so good. Fresh and fast deliveries without any stress.
