Asda Delivery Driver Rushed Me Despite My Disability and No Option for Help Inside

My most recent delivery left me really annoyed. The driver obviously noticed that I was crippled and straining to control, but instead of providing any kind of assistance, he just kept rushing me ahead as though he were in great haste. I understand they have schedules, but a little understanding and patience will help greatly, particularly when it is clear I need some more time. Even if I'm ready to pay extra, what disturbs me even more since it seems there is no way to ask for help. There ought to be a way to get some assistance carrying the groceries within. For many in my circumstances, it would make a significant impact.
