Samsung S6 and Gear 2 - That doesnt properly

I got my upgrade in Sept 2015. I am deaf and require a phone with Telecoil. Not many brands have phones available & I was disgusted with Sony so I therefore did some research & decided to go for a Samsung. I am extremely disappointed and unhappy. 1stly I am still awaiting a response on a email send 2days after getting my phone whereby I requested info on how to switch telecoil on and off. I am yet to receive a response and subsequently discovered its on auto. I had a Sony SWR10 with my Sony phone & it was the best thing I had ever bought as I never missed a call or msg again. Unfortunately its not compatible with Samsung. Vodacom never advised me I cld've added the Samsung Gear S to my contract so I got a Gear 2 2nd hand for my b/day that the previous owner only used for a month. What a absolute waist of money! I have missed more calls and msgs with it than without as it has created a false sense of security so I don't check my phone as often as I should. Unfortunately because I am deaf this is not a want but a need & I'm beyond disgusted. The watch was suppose to assist and make my life easier yet its done the total opposite. my phone battery doesn't even last a day @ 3mnths old.
