Do not buy a Fitbit from Dischem

I recently purchased a Fitbit from Dischem. The purchase was made on the 31st of December 2017. I am not happy with the product as it is inaccurate. Distance is recorded incorrectly aswell as heart rate. When approaching the Dischem Nicoleway store I was told that they can not refund me as the first need to send the device in. The issue that I have with this is that firstly Fitbit has a global 45 day refund policy, this is obviously something that Dischem ignores in South Africa. If you wish to give back the device in South Africa they now first have to check the device ( so you have to send it in) and only then will they consider a refund????? I am not happy with the device due to inaccuracy and I would like to purchase another device so I can continue to earn my vitality points - I shouldn't be inconvenienced and stuck without a device while Dischem protects their own book. They are giving Fitbit a bad name.
