Dissatisfied clients

Bought a Vivofit 4 that sync for a second and then disconnect. Been trying for 2 weeks now. Obviously nothing is working as it should. Doesn’t count steps etc. been speaking to Terence Michael that’s been giving me the run around. I just want them to collect the item and refund me. His last message to me was that they have a 14 day return policy and therefore it has been rejected. I sent him their policy which states that there os a 30 day return policy. Haven’t heard back from him. There’s a lot of other duck and dives from him as well. Please could a manager or someone that can actually assist me please call me.
