I called omsi regarding a medicated shampoo.I have been informed that stock is available and even online while placing order the site showed availability of stocks.But while I tried to reach them they didn't pick up my calls.On wats app they told me that stock is not available and also told me to alternate the product.But when I refused and wanted refund they didnt reply ro my calls and messages.I already paid by debit card.Dont know what ro do.
