Netmeds — Not delivered till yet

They Send me wrong product for which I return the order and exchange it but it's been 15 days they are not giving me the exchange order nor they refunding me. When I asked for refund they said me to give it in my netmed wallet which I don't want because they don't have that product. I have to purchase from else where . And they refund me the amount to my wallet which is totally useless. I am paying 1800 for a medicine and 1800 I don't want in my wallet. They should change their policies or else quit . This is not a solution I had to suffer a lot for netmed.
