Adidas — Negligence in refunding the money.

I recently placed an order in the adidas India website app and the order got delivered but as it was a size larger and loose in fitting i got it returned and as per the return policy of adidas…we can expect our money back in 14 days max although for me its been around 20+ days and they still have no clue why they are not able to send the money back as they keep saying technical glitch and our technician team is fixing it continuously delaying my request.
