Bad service from Samsung online store!

I purchased a Samsung Watch sports band on 5 January. It arrived on 7 January, but I noticed that the band supp**** with my 40 mm watch was small and tight, so I didn't open the extra band I bought from the Samsung online store, as it was also a small size and I knew it would be tight. It appears that the 40 mm watch comes with a small band.. not sure why consumers are not given an option to choose! I called to request an exchange for a medium band. A ticket was logged for me on 8 January, and I was told the exchange would be completed within 10 to 14 days. I have now been waiting for more than a month for them to collect this band and either exchange it or refund me. This is unacceptable, and I have not received any updates. I was assisted by Simphiwe, who opened a ticket on 8 January: inquiry ***8. When I call to check today, I'm told they still have to check the stock... chances are I'm going to wait for another month! You can't even return to their physical stores! Phathetic Samsung!
