State Bank Of India [SBI] — am complaining about wrong deductions

Can you please help me with below complaint

There are 2 debits of 444 which pos vendor in indira nagar bangalore says he did not receive and made me to pay money through paytm (5th september), after few hours i saw deduction one on 5th sep and other on 6ht sep 2018

Pos indiranagara has shown me his statement and i did not see any amount he received. He already receieevd 444 from me on paytm saying transactions did not happen because of network issues

Although am requesting him softly to help me, he is harsh and saying go and check with your bank

He has swiped twice and said transaction did not happen because of network issues. I see amount deducted twice one time on 5 septemeber and one time on 6 september,

He said both the transactions ddi not happen and took money from me

I lost 888 rs unnecessarily
