Khazana Jewellery — Silver quality poor

I purchased one silver chombu, I use yearly twice for Pooja.Its started rusting inside and it had very small hole( dot size).I submitted to polish and repair the small hole, they told they have to send it to Chennai as they don't have repair facility at Bangalore they took one and half month time.After week without my permission and information they tried to repair it and made big hole and told me to collect the chombu without repair.

By paying for silver is i bought iron ???

What kind of service and quality u people are providing to customer by collecting silver price?
