Hello Hoping someone can help my sister. DS is claiming universal credit which she set up over the phone ( not technically savvy). She notified them by phone of her DH pension increase and she thought everything was fine. Couple of days later she received a letter stating she owed them £200 which they took from her next payment - leaving her very short of money ( I’ve given it to her but that’s not the point) this is a mistake as pension only went up £17. She has called them every day for 14 days and each time they say her case worker will call her between 8-6. She has waited in every day and no one calls. Husband has had a stroke so they’ve been stuck in doors all this time. She is distraught as she thinks they’ll take it again when next payment due. I’ve tried to set her an account up online but it seems you can only do this when you originally claimed. I can’t find an email address to contact them either. Is there anything we can do? Really grateful for any advice. Thank you.
