Appalling service on closure of account. Mothers house was sold, mother was in a care home, not at all well. As her son with POA I advised of change of ownership of the property and tried to close the account. Despite providing copies of POA, one month later after numerous communications UW are still unable to action and provide final bill. Mother has died in the interim and still they have not sorted. The responses are appalling. Every other service provided sorted the House sale with one simple telephone call. I raised a complaint and was told would get an answer within 5 days, 13 days later still not sorted and even though I have raised complaint they ask me to contact via their main contact number which takes usually 30 minutes for someone to answer. They have no customer service ability at all and no empathy to the situation. Quite simply appalling at this very emotional time.
