what is the best internet plan?

im looking to change internet providers as team telco changed companies to 2easytelco and they have done nothing but try to scam me. at current i have sent through a complaint to the ombudsman because they changed my usage from 25gb to 5gb and wont fix it.

i currently have adsl2 and live near wyong so not all are available but i will find out if you just let me know which company you think is good.
