How to express thank you in different way?

[Supercom]

I am a EFL learner. If someone helped me a lot, can I say I own you a pleasure? Or there are other ways, I can express my thanks to the one who helped me a lot?

[Torsten]

You could say I owe you a lot. Please note that the verbs to own and to owe might look similar but they both have completely different meanings.
By the way, you are an EFL learner and we are happy to have you here on the forum. Keep asking questions and sharing your experiences.
Talk to you soon,
Torsten
