Scammer is watching you online

Yesterday I received a call from Vodafone saying that they didn't receive my payment in their system and then advised that they would fix my internet because it was very slow sometimes.Slow sometimes And sometimes it's fast He continued to send me messages and took the OTPs while he advised me to stay on RHW line. After that, I read that he used my mobile number to pay and he purchased For the price of 5000, that's when I was surprised and talked to him, he wasn't calling from Qatar but from outside Pakistan. That's when I found out that he had scammed me and I ended our conversation because I knew.he's doing to me is not right because he wants to get all the information from me so that I will pay for what he did to get that thing. It turns out that he's a scammer. He's bad at what he does.
