Myntra.com — cheating with customer

Address: Viajy nagar indore, Indore, Madhya Pradesh, 452001

I have ordered two product from myntra ad 22nd april i got only one product in that parcel. I raise the complaint against the same to customer care they have filed the claim and told me to wait for the next 3 days that is still 25 april after we will resolve your issue.
Till date, there is no communication from there side. Today on 26 april i called up to the customer care of myntra asking for the resolution again they are saying you have to wait for next 24-48hrs. Due to the wrong information is entered by the customer associate.
They are unable to resolve the issue. My question is this to myntra.com that what did you do in the time duration of 22-25 to april and why they are asking for more time.
Myntra is cheating on customers.
Kindly check and take neccessary action against his company.
I will also lodge complain to a higher authority
