I bought some batteries from Tayna just before the Christmas period. Through no fault of theirs the batteries got lost/found/lost/out for delivery/lost/found etc etc repeatedly by the courier company. Throughout the entire fiasco Tayna kept in constant contact, offering just about every option inc. a full refund or replacements which would sent out as soon as the Christmas/New Year chaos was over. I eventually opted for the refund and replacement route and Tayna re-delivered the items by another courier with no problems whatsoever. Would I use Tayna again? 100% yes - they showed their true colours by giving me a further discount off of what was already a great price for the inconvenience and didn't shy away from the problem in the first place.
