I ordered a new battery for a v8 on 2nd February. After 2 weeks I still hadn’t received the battery and I contacted their customer service. I was told that the part was out of stock and to try to find it elsewhere. I was told I would be refunded. However it is now 6th march and I still have not received a refund. I have called many times as well as speaking to online chat and each time I am being told my refund will be processed soon. I will never ever buy a Dyson product again due to the horrendous back up service.
