Vasan Eye Care Hospital — Double payment

Address:

Vasan eye care , HSR

Visited Vasan eye care hsr layout yesterday. They asked to pay the consultation fee. And they said they would not accept card but would accept cash or phone pay/ google pay due to pandemic. I tried phone pay . First they did not give the scanning to scan but a number . I was not able to pay to the number because it was not in upi network. So the lady asked another guy to check on that he gave a number to which I could send amount 250 . Payment was done successfully and showed it to him. He said that’s not the right no. And asked to pay the cash and argued I had to pay the cash to get the consultation. So I had to pay500 for a single consultation . Frustrated me. Why do Vasan care has personal staff numbers as phone pay account to pay.
Instead of scanner. There is no logic in this that they would not accept card but cash and how would this is safe they think?

Please look into this and refund my amount.
