VLCC — Laser hair reduction full body

Address:	VLCC HRBR layout Bangalore
Website:	Vlccwellness.com

I have paid for full body laser 7 session in HRBR layout Bangalore feb 2020 but due to covid i could only take 2 sessions.
Now i am in pune and telling them to transfer my package to Pune they are saying we have raised your bill in some other service so we cannot transfer your package and you can avail promised services in Banaglore only.
When i asked about bill in Feb 2020 i was told we will edit and give you bill in next visit.
Next visit was May end i was told accountant is on leave we will give you relevant invoice in next visit.
I am feeling duped by VLCC. My money is stuck they are not giving me service.if you cannot provide promised services kindly refund my money.
What kind of scammers you have hired as employees who promise something and then bill something else.
