Address:

Hyderabad, Andhra Pradesh, 500084

Dear sir,

I bought a refrigerator from bajaj electronics from kondapur branch. I paid inr 52, 600 for lg refrigerator model t542 gnsx. Value of the invoice provided to me is inr 64, 900. When i requested kondapur branch to provide the invoice for the actual amount paid, they said this how they issue invoices and i need to reach panjagutta office for any clarifications. I tried reaching on numbers provided. There was no response. Because of difference in invoice and amount paid i am not able to claim the amount from my office. Please provide correct invoice.
