Zivame — Trying to call on provided number to return the wrong product but no response

Address:	Hyderabad, Andhra Pradesh, 500032
Website:	Zivame.com

I have bought a product which has a size issue.
Following the steps to return/replace the order I am trying to return the product but the number provided is not responding.
From past two days its saying pls call tomorow.
Also there is no convinient othr options to put a request of replacement/return.
Even the company has nothing to do with the customers whether they are liking the product or not.
Worst service
