If you used the BT directory enquiry number 118500 between September 2011 and January 2014 you could be due for a refund. The telephone giant was fined £225,000 earlier this month for a directory enquiries rip-off. The service carries a connection charge of 59p and then £2.39 for every minute you're on the line.
People who dialled the service were kept hanging on the premium-rate line with recorded messages without being warned of the high cost. One customer is thought to have run up an £81 bill while another was charged more than £450 over three months for using the number-finding service.
Anyone who used 118500 in the period can apply to get the whole cost back. Register your complaint by email at firstname.lastname@example.org. Say you are claiming a refund following the PhonepayPlus tribunal decision 17976.
You'll need to have details of calls made to the service but they should be included on old BT statements. You'll also need to give your BT account number and name and address.
