Jewellery insurance

I had a bad experience with jewellery insurance sterns. I launched a claim on beginning of February 2020 where i lost a watch and put a claim at sterns goldfield mall. All the months past by without any acknowledgment that they received my claim. Later 15 September 2020 i called them and promised to attend to it but nothing happened. Each time when i call i am given excuses that assessor is looking into it, the last excuse was that my voucher is ready and they will send it to the store where i bought the watch next day. Till now i am still waiting. It is like even their consultant are trained to lie to client. I am so disappointed by this Jewellery insurance. Every month they get their money from me but fail to meet their responsibility.
