Poor service from Dischem

I bought a Fitbit watch which malfunctioned after 6 weeks, this is the second one dying on me by the way, I took the phone back last week and haven’t heard a peep from Dischem, that time I’m losing my vitality points because I cannot track my fitness activities which is the main reason I got the device in the first place.

I paid for something that’s not adding value I’m missing out on benefits, I just want my money back from Dischem that’s where I got the watch. Dischem can sort this out with Fitbit whenever but as for me I want my money so that I can get a different device

So pls I want my money
