I have one day paid through Key and another by ISS. The one day through ISS was promptly paid, but, but my calculations, I received about £3 less than I would have on PAYE. For the other day, paid by Key, which I did in November, I am still waiting. E-mails, phone calls, letters: all bring promises of action but nothing else. I have considered using the SCC procedure, but the cost of doing so is more than the earnings involved.
