Lemontree Hotels — Wrong GST Number on the Invoice

I have stayed at Lemontree Hotel, Guindy, Chennai from 12-14 Oct 2025. Upon checkout they provided the Hotel invoice quoting HPCL Andhra Pradesh GST Number instead of HPCL TamilNadu GST Number. The receptionist and her manager they don't have the access to correct the same and gave the finance e-mail ID for correction. But the finance is not responding upon the receipt of the e-mail. The online booking (whom I have contacted for Hotel booking) also couldn't resolve the issue.
