How much effort to sort out overpayment?

[formant]

I'm with one of the larger, fairly reputable umbrellas. I'm pleased with their service generally, aside from the fact that they seem to be so efficient, that they're making mistakes. All in my favour so far.

Most recently they've overpaid me. Initially they paid me the right amount, but there was a typo on my payslip. Two days later I received an additional payment and a new "rectified" payslip.
Now, I'm a terribly honest creature, so I queried the payment. I get the response that this is all fine and the payment was related to my expenses.

Well, yeah, even I can see that. Rather than subtracting my expenses from my gross pay they added them to it.

So...should I keep chasing this up? Would you? I'm getting a bit tired of having to spell out their mistake in great detail when they seem rather disinterested. Should I just forget about it and keep the cash (at least until they do notice)?

Advice

Dear formant,

That is a hideous experience!
I know for a fact that many companies out there have problems processing payments.
Also almost none take the risk to give the client a "quality experience" in terms of payments.

Many companies take the risk of processing money in less than 24 hours - if that isn't done then no fees are charged. Unfortunately not many companies can do that out there.

In your case it really depends on what works best for you.

If the umbrella company has efficient processes in place their internal checks should tell them that an error has been made and they should then notify you, apologise and correct the mistake. It would also be good customer service to process your next payment free of charge.
