Bank Of Baroda — oneplus 6t

Address: Ghaziabad, Uttar Pradesh, 201011

I ordered a one plus 6t on 4/11/2018 in exchange of a redmi note 4 for 34, 063. It wasn't delivered as the redmi phone had some scratches on it. So i was asked to order it again and my refund was promised in 2 days. Later, as i have a government bank account it was promised on 17th of november. I still haven't received it but they're insisting that they've initiated the refund on the 7th of november and it is the banks' fault.
