Great Eastern Appliances — Non change of address and name

Address:

Kolkata , dakshineswar

I bought my carrier spil ac on June 2022 from great eastern bt road kamarhati . My mobile no [protected]. It was in the name of State Bank of India as I will get reimbursement of the bill. In the place of delivery address my name was missing in the bill. I told them to add tha name of me at the place of delivery. Staff informed me it is not possible. But due to not prence of my name in the bill my authority rejected my bill. Please suggest me can that bill be changed.
