the whole point is to advise atc you are ''going around, or MISSED"...if there is a bonafide radio problem, fly the published...what can you do? but if they say, fly runway heading maintain 3000 contact approach...that's what you should do.
mind you, you could be really cool and ask in advance...if we need to fly a missed approach, do you want us to plan the published or are there alternate instructions?
