Apple India — AirPods battery draining issue not resolved

I have submitted my AirPods in Maple Authorised Service Centre Khar Branch Mumbai. They are not ready to revert back since 4 days and now got the email that they want to observe it for more 5 days. I don’t expect this kind of service from maple. I have paid 10k for that device and this is what the service I’m getting. Even after submitting the genuine evidence for the issue I’m facing.
My work order No.
