Reebok India — fake shoes quality check by reebok

Dear recipient,

I bought a reebok shoes through reebok official website by 16th mar 2019.
I received the same on 21st mar 2019 & i try the shoes but it is a little short from my size.
Then i put a return request to reebok by 27th mar 2019 & they cancelled my request without reason.
When i called again & again to reebok customer care executive then they agree to accept my request for return.
I wait till 5 days for the pick boy, but nobody come for pick up.
Again & again i called to reebok customer care & they ready to pick up & they pick shoes by 10th apr 2019,
Now they reject the shoes for quality reason without any information.
When i called to reebok for checking my payment received status then they inform me to the product (Shoes) has already failed in quality.
They said that the shoes has used, but i didn't use it.
Now they are not ready to explain more details o[censored]se the shoes.

Request you to sir, please arrange my refund payment from m/s reebok.
