unhappy with product and service

i have always used the twisp clearo device and have never found any problem with it at all. I go to twisp on a often basis and consider myself a loyal customer. However 3 days ago the top half of my battery would not connect to the battery therefore i was unable to use the device. at twisp i was told it was not repairable and i would need to buy a new top half for 200. I asked if they still sold the original clearo and was never given an answer. I was told that the new edge would not disappoint and is the upgrade of the clearo and should buy a new device as mine is old. I bought the edge and after 1 day found it disappointing and not as satisfying. i went to the store and asked for a exchange for something else as the edge was not satisfying. i was told that i will NOT get a refund and will not be able to exchange the product. I only had it for one day had all the parts and extra coil and slip and was told theres nothing the could do about it. when i told to the manager my situation with my clearo he fixed it within 5min. I was so upset that the sales rep did not try help me fix my clearo or even mention to me the clearo still forsale. now i have a device im unhappy with- unhappy
