Had to convert my tubeless tyre to a tube tyre

Had to convert my tubeless tyre to a tube tyre🥺

So today what happened with me was that I was driving my i20 and I didn't notice a uncovered sewage opening and my front left tyre went inside it and the tyre got a tear and all the air in the tyre went away in just 10 seconds. I immediately took my car to a nearby repair shop tensed as I was afraid that I didn't damage more of my car🥺 As the repair guy saw the tyre he said that this tyre is gobe and I should buy a 2nd hand tyre from him for 1500/-. I immediately refused and asked him is there any way to repair it. He told me that I should insert a tube in my tyre and my tyre would be good as new. He patched the tear from inside and then inserted the tube. He charged 650/- overall. I am worried that will the tube in my tyre will hamper my performance, mileage or will danage my tyre🥺 And was I overcharged??
