RAC will not refund any money,
especially if you are talking about any extended period of time,
Even if it is only a few weeks,
they will tell you that you pay in advance,
and even if you pay by the week,
you have already had the item for the time the payment was applied.
In many years,
in several states,
I have never known them to give a refund or even a credit on returned merchandise.
They think it is their divine right to keep all your money,
for gracing you with their greatly overpriced merchandise.
