can you provide a phone number so I can actually speak to someone , have spent many hours trying to sort this with no luck. PLEASE

I am also having this problem when trying to log onto GovGateway, have rang 0300 200 3600 but it takes me through the options and then rings off. Went to Income tax : general enquiries and that was of no help. Please help, been trying for hours to sort this.
