Yes, I can understand that you get a bit frustrated. I was forced to get myself a new cable (and FPs own charger) as well, since my old smartphone had a mini USB contact while the FP uses a micro (OK, there are adapters, but they are far too clumsy to fit the case - plus that a complete cable is often cheaper).
And there are 3rd party USB cables that fit without any trouble. Mine comes from Exibel, and I’m sure there are a lot more.
If the placement of the USB contact is a nuisance, e.g. when using it in your car as a GPS while charging at the same time, see this thread about allowing screen rotation all the way round: Which app if I only want phone upside down
