Capital One Credit Card Complaint

Capital One Credit card department,

Transaction issue California

I purchased a - from an - seller and it was not as advertised. The product was damaged. I contacted - support and they asked me to return the item back to seller and I provided both seller and - with a tracking number. The tracking number for the item I shipped back is - -. - told me they could not refund me the amount owed. The product is $1000.00 and I paid an additional $89.00 to ship the item back to seller. I called Capitol One and asked them to dispute the charge of $1000.00 after I gave them the appropriate documents by email and also submitted to them the tracking number for my return. Capitol One told me I had to wait 10 business days to receive a refund. I contacted them again after 10 business days and Capitol One told me to wait another 10 business days. I feel like I will not be getting my refund of $1000.00 especially when the tracking number proves I returned the item back to seller on - -, 2016 and I am still not issued a refund. Capitol One is also charging me interest charges for the amount I am disputing as well.
