hi friends, Kindly help me... I have just started my online shop. I had shipped around 120 coins to one of the buyers in chennai. However, he has filed a complaint against me and said that he has received only 20 coins. I had arranged it by speed post and am confident wasnt opened in transit. Knowing not my fault i still offered the remainder coins by courier, however the buyer has refused that and wants to cancel the transaction. This means he keeps 100 coins and sends me 20 back. He has paid via paisapay. Kindly help on what do i do now?
