Konami — PES 2021 Mobile Myclubcoin purchase

Website:

PES 2021 mobile

Minutes earlier I purchased 300 my club coins on PES 2021 mobile for Rupees 89, after completing the purchase on my bank's(SBI) site, I received a message few minutes later saying I was debited by the sum from IBN TXN or something like that. I didn't understood actually on who's behalf this message was sent, but I thought as purchase is completed I might receive 300 coins inside few minutes.
Time passed by and it didn't came. I searched Google and got link to few such complaints on reddit/other sides about same issue. Some of those were 2 years earlier yet they recently updated saying they eventually never got the coins or refund, they payment was succeeded. Only after that I realised it was a fraud, Konami is a HUGE scam. Now my case is recent, and I don't want my club coins anymore.. I just want my money back as soon as possible so I can stop playing this game forever and suggest people to do so or at least to not make purchase
