Lies and Deceit

I purchased a ring from another jeweller and as they were unable to resize the ring in time for christmas i took it to American Swiss Secunda. I was told it would take about a week to resize. Today the 21 december i picked up the ring as i was told it was ready and was resized. To my disappointment upon inspection of the ring the centre piece of the ring was loose and chipped the ring was dirty n had scratch marks. I spoke to the consultant who informed me the ring wasnt even resized yet damaged,and should come back on the 2nd of January. I find this totally unacceptable and appalling. Its four days to christmas and i am told to wait until the 2nd. This was purchased as a gift for christmas. The question is what should i do now. Is this the type and quality of service that a trusted brand gives ?
