Nykaa.com — partial order received

Address:	Ahmedabad, Gujarat
Website:	www.nykaa.com

I had ordered 2 M.A.C products i.e. Mehr lipstick and Prep+ prime from Nykaa on 5th July, 20-8 and received the order on 7th July, 2018 but only 1 item was present in the package. I have tried contacting Nykaa in several ways but i couldnot talk to anybody and noby responds to the email and phone calls. Please help. I have no other option and the bill and app says that both items have been delivered but actually only 1 item has been delivered.
