I phoned the 7777 number on the 16th. After going thru security was told no Life Cert, (which I never received). I explained the situation with regard to the lack of mail. I was then told that my pension would be reinstated and I would not have to send them a Life Cert. Pension arrived 21st. Hopefully this will keep them off my back for a couple of years.
BTW. I used this company to make the call.
