Zepto — Issue related to "Refund not Initiated"

I have ordered mangoes on 2nd April and received damaged products. And raised complaint immediate next day 3rd April. They told Amount initiated with in 7 days. But no refund received. On 20th April I approached customer support and they told order is older than 7 days They simply change words and try to blame customers. In between I wrote a mail to customer support with an attachment of product pic. This is very pathetic. They blame customers. They don't have any respect. Help in this regard. I lost my money because of their mistake.
