Diyan Enterprises - Incorrect order received amount debited twice no refund processed

I have placed order for two quantity of “premium **pcs line printed storage container” seller sent quantity of * hence I have placed return they took return and credit amount for only one and there is no proper response from the customer service,

They are like you have to checked the order before placed and blaming it on me and unwantedly placing the call on hold and disconnecting it is this how you run a business. No proper support or professional behaviour of customers services agents worst
