Currently the FOS is upholding 90% of PPI mis-selling cases referred to it after they had been rejected by the banks.
Wheatley says it is "absolutely not acceptable" and that it is "outrageous" that the number upheld by the FOS is so high. He stated that the FCA has been looking into how banks handle complaints, as per the Telegraph:
"We have taken action and we will take more action and we will continue to look at how banks handle complaints.Sadly PPI mis-selling is but one of many areas where Britain's financial services industry mired itself in its own shit.
We've got two large investigations underway and have two cases where we have issued strong fines."
