I agreed to a payment for a job that I’ve never done before, for a friend’s family. However, after doing the job for a month, I realized how much I was being really underpaid. I never said anything, for 2 months afterwards, to avoid conflict with their family.

I want to bring up the issue because now I’m feeling to not care to keep family peace because I’m feeling taken advantage of and would like a compensation for all of the money that I should have been given for the work I did in the past. However, at the same time, I agreed to the initial very low pay. So, I understand that maybe I can’t do anything now since my new-experienced/unaware self agreed to the payment. Thoughts? Thank you very much.
