Well I decided to give 150 another go and found that if I pressed the option for technical support, I got to a real person who was not a sales person. He was really, really helpful. Explained that the money I had paid for the monthly contract would be recredit to my bank account, then credited with my payg with the 60p that had mysteriously disappear so I had £10 and then set up a £10 payg pack for me which I can make a subscription pack in a month's time. Well done him.
