Contacting O2 to cancel airtime plan

[Triciacarol]

I spoke to a customer service advisor this morning. The bill is in my husband's name. She asked to speak to him, but he is in early stages of dementia and does not remember his password. She got him all confused and he asked her to speak or me on his behalf. Anyway, he has finished paying his device plan so wants to cancel the airtime plan on his tablet to save money. They wouldn't cancel because he didn't know his password. He said how else can I cancel this for him. Also he wants to go sim only on his mobile. They told us we had finished ourdevice plan lats month but the bill is the same this time. He doesn't converse well with people and I do all his calls and paperwork and for him. HELP. What can I do. I think the customer service is abismal.
