Nationwide and NatWest say they have fixed IT glitches that left customers overdrawn or unable to access their accounts.
The problems left nearly 750,000 customers of Britain's biggest building society, Nationwide, out of pocket after debit card payments were taken from their accounts twice. Nationwide said it corrected the errors on Thursday and has promised to reimburse those affected.
NatWest, rebuilding its reputation after a huge IT meltdown last month, saw its online service freeze on Thursday. NatWest said yesterday that its online service was working again.
