[Resolved]  Flipkart — installation charges for returned marq ac

I purchased ac from flipkart which was defective, when i requested for replacement there was no replacement available only refund option was available.
Then i have returned the ac and got refund at the time of returning i asked about the installation charges to customer care they said it will be refunded in flipkart wallet (See attachment of mail thread).
Now it is more than 15 days still they are not refunded the installation charges, i have called many time to customer care they are opening the incident but they are not able to resolve it. (Flipkart incident# in[protected] it suppose to be resolved by 25th april but not resolved, when i called today (1st may) they are saying we have escalated the issue give us 48 hours, same thing they told 3 days back (27th april).
I request to take the action against this issue
