Hi thanks everyone for your replys which have been very helpful.
Lapsed Workaholic in answer to your questions I was told of the sign on appointment on the previous sign on appointment. The advisor told me i was due to sign on on the 22nd but not to come on that date but come on the 26th instead. The evidence I have is the date 26.6.15 uc which is what the advisor wrote in my Job log as a reminder. The receptionist said I didnt havs an appointment very rudely and telephoned upstairs and was given a new sign on date which he told me. The sanction letter came from Universal nnCredit. I have a quarterly check of my Job search on Monday and have been asked by Universal Credit to take my proof and show my Job Coach and they have to ring uc and tell them they have seen it. I hope this answers your questions. Thanks for your advice.
