If for any reason — comma?
A comma is not needed in If
for any reason phrase. So,
If for any reason something…, then
something…
If for any reason you are not satisfied
with the quality of our services, we will refund your money back.
If we really want to put a strong emphasis
on for any reason, we may put two commas:
If, for any reason, you are not satisfied
with the quality of our services, we will refund your money back,
but without commas it flows better.
