Terrible service!

I bought my husbands wedding ring in July 2015, we got married November 2015 he obviously only started wearing the ring in November. It's 2 months later and the condition of the ring is terrible, full of scratches and looks like it's 20 years old. I took the ring to the canal walk branch and was told that they cannot do anything?! I could not believe that a company who's considered one of the biggest jewellery stores in south Africa would not take responsibility for the condition of the ring! I would like to be contacted by a manager to be assisted further as it find this unfair and disgusting!
