I would ring and demand to speak to a supervisor and get them to deal with it directly - I have a had a similar situation before. They cannot just cut her off if she hasn't requested it. Also contact the bank and block the payment - again they can't take money for something you have not requested. When she has it sorted I personally would change companies out of protest. Maybe ring them on her behalf - she can authorise you to speak to them and give them hell. An unhappy customer is not good for business. Make sure you take the names of who you speak too and be polite but firm.If the supervisor doesn't help move up the chain, demand to speak to their superior and so on until you get the situation sorted.
