I have had to update universal credit as my partner lost his job. It was easily done online but I still then had to phone. I thought I’d be waiting ages but actually wasn’t that long and sorted the situation out quickly.
I also then had to go to the job centre in which I didn’t have to wait long and the person who saw me was kind and compassionate to what I had to say.
I have personally had no problems in regards to the job centre or DWP.
I am currently helping my mum who has help with several people and one thing we have found is when they are to call you, somtimes they ring for 2 rings then hang up. In which has resulted in a sanction as they then say you missed the appointment but when proved they rang for literally 2/3 seconds they changed the sanction.
