As has already been said, we don't have all the facts. Your aunt definitely needs to get a benefits check from CAB.
So far as the friend is concerned, if she is getting £70 on top of her state Pension it almost certainly means her state pension is low - probably around £72 per week. Payment for a cleaner is nothing to do with benefits - if it is being paid by anyone (other than, possibly, a local charity) it will be social services, but I'm surprised if they are actually paying for that type of thing.
