This is to inform you that we have purchase sony brevia 65" in your reliance digitel at haldia unit on dated 30.9.19.

They had commited me that one sound bar will be provided at price 10990 for absolutly free. We had agreed. But unfortunately we had paid only 50k, could't transaction complete. They had replied me that next day 1.10.19 we had completed transaction but store associate replied me sound bar will be delived which was committed. But free days later they had delived sound bar which price is 5498.
