I ordered 4 x 280ah lifepo4 cells on 10th November 2020 and I have still not received them. I have asked for a refund from the seller with no response. The past 3 weeks I have gone through the Alibaba refund process only to be told they will not give a refund even though they know from the tracking that I have not received the cells. I have now started a chargeback through Barclaycard. I'm in the UK and now have to find another supplier to buy from who won't keep me waiting another 5 months
