can someone please tell me how can I contact AdSense team?
If you want to directly contact AdSense Team Members, then you should be a Premium AdSense Publisher.
If you have questions to solve, try asking the same in AdSense Forum (Official)
can you help me with the link of forum
Oh Sure, Here it is: https://productforums.google.com/forum/#!forum/adsense
Do you mind if I ask, what is it you wanted to ask AdSense support? We all use AdSense here and might be able to give you good advise. or give a link to where the question is answered.
