I sold some inherited gold when the price was at all time high earlier this month. But the jeweller gave me a cheque at that day's market rate and asked me to cash it only after a month. I agreed because it was a good offer, other shops were deducting 4-5% from market rate. Also I had earlier bought jewellery from him so there was no trust issues. But now that i try to contact him he is evading and the cheque has got rejected. I only have this cheque in hand no kind of other evidences regarding him owing me money is there. What is the way to go ahead now?
