Maybe a good place to start would be to remember that pretty much every serious economist accepts that the UK gets back far more than £350 million per week by virtue of our membership of the EU, and indeed that leaving it, especially with the deals proposed by the Tories, will make the country, and the government, significantly poorer and therefore less able to invest in whatever it wants.
Which serious economists? Who decides how that money is spent? And in what way does the UK get back more than it puts in? You referring to VAT-savings due to in-EU trading? That doesn't count, clearly. But sounds like that's what you mean when you write by virtue of our membership of the EU.
Theoritical trade savings can't be used in any serious argument about numbers until we know what kind of deal is in place post-Brexit regarding VAT within EU trade, and what could be surplussed from future non-EU deals post-Brexit. No serious economist would abuse the figures in this way, only those who have been assigned an agenda by their employer (institute/thinktank).
I linked a serious piece saying the UK's net contribution last year was around 9 billion sterling annually. Or let's call it net loss.
Here's an official government source which again confirms the UK loses more than it receives, to the tune of 8-11 billion pounds (net) depending on how you calculate. They don't consider VAT trade-savings because those figures don't belong here:
