Should I ignore 271 notices after tax closure proceedings initiated?

Hi Sir, We received a 147 notice about 2 years ago, and last year, the closure proceedings were initiated with no tax payable by me. In fact, there is a return/refund available in the closure statement. After the closure proceedings, 271 notices were issued, but our tax agent suggested ignoring them since the closure proceedings were initiated and the tax payable is 0. Please advise if these can be ignored or if any action needs to be taken, as we are getting reminders with tight deadlines. Our tax agent mentioned that these are autogenerated emails and can be ignored. Please advise.
