Disaster! Specifically picked this company due to their 'next day delivery guarantee'. Took the day off work to wait in for the delivery of the battery, at 11am had had no communication with a time slot. Contacted The Battery Guys via live chat who confirmed the battery hadn't left the courier sorting office but they would get back to me with an update. I heard nothing but a few hours later randomly received a full refund! Again contacted via live chat and it transpired they had made an error and only intented on refunding me the £1.99 delivery charge. They gave me two options, cancel the order or order again and they would make sure the second battery didn't get despatched. I checked again if it had actually been despatched and they confirmed it had. This confused me, how can the order be cancelled if the battery is with the courier! Anyway, fed up I cancelled the order. I can only assume they never actually despatched it or how could they cancel it after despatch? Very dissappointing as I wasted a day annual leave waiting at home for no reason.
