Dear sir/madam,

I went to go reliance market, guwahati (Tripura road) dtd.24.10.2019 for purchase diwali gift for official purpose & household items as other days. After searched my required items i go to cash counter to billing towards my items. I have been successfully paid my amount to rs.3661.52 through google pay vide upi transaction id[protected] dtd.24.10.19, 5.37 pm (Transaction details attached) but, invoice not generated on reliance market system. I shown successful transaction details (On google pay & messages) to cashier (Mr. Zubin sharma) but he didn't accept & force me to repaid the said amount and he forcefully suspended my bill & transaction details on his system. Then i told him, i want to discuss with his senior. After talked with mr. Rajesh gogoi (I think he was store maneger) & after 2 hours met floor manager (I forget his name) to discuss about the same. But, they also force to repaid the amount if i want to take my items and he formally lodged a complaint on his system. After 3 hours they mentally harassed to me & i repaid the bill amount rs.3661.41 dtd. 24.10.2019 on 8.11 pm vide bill no.156 & transaction id[protected]. Now my question as follows:
1. After successful bill payment why i havn't get my items?
2. If bill not generated or else its my fault?
3. Why they mentally harassed me for 3 hours. Where is my fault?
4. They havn't seen the amount credited reliance account or not. Its customer fault?
