Not backing up products

I bought 3 Polar Loops from Totalsports. 1x Blue, 1x Black and 1x Purple. I have none stop problems with these activity trackers, they are not accurate, there batteries last two-three days with no activity being done?? they don't sync to smartphones its just disastrous. I have been back and forth many times to totalsports who just say to me they have to send it to polar and they will check it. I told them on my last visit if its not right i will go in and make a scene and this is my last attempt before I carry out with that scene. these watches have been to Polar way to much i think they have had it longer than we have!!!! o and IM STILL WAITNG for them to contact me with regard to the black and purple one which I had to call totalsports about for them to tell me its back in the store and I can collect it. I am sick and tired of people messing me around!!! Sort this out or I will take it further. I'm finished wasting petrol and time on polar and totalsports.
