Silver plating of a Swarovski ring

Took the ring to the Swarovski branch in Brooklyn mall. Asked a lady by the name Lebo if she could assist. The silver plating on the ring started to fade, yes she answerd we could send it for replating. Lebo said she will send it and quoted R650.00 for the repair. We waited 4 weeks and then phoned she rep**** the ring is on its way after a week we phoned again but they could not find the ring then they send a photo asking if it was the ring and yes it was. On arrival we now had to pay R395.00 cash and received a cash slip with another companies name on. When we opened the box and inspected the ring closeup great was the suprise that nothing has been done to the ring at all it looks like the day we left it for repairs with Lebo. We had to pay the R395.00 as the very arrogant lady helping us refused to give us the ring if she does not get the cash, we pay and left. I smell a really big rat and is sure that this cannot be the way that a elegant smart shop like Swarovski would operate. We still have the cashslip and the ring like we received it. It would be great if there could be feed back if this is the way Swarovski operates in South Africa !!
