Pensioners gets mistreated when want to pay account

I wish I could give 0 stars, I am a pensioner just trying to pay my account, but as soon as I call, I get ignored. When I try to email, they just ignore me and charge me to email them. When I try to make an arrangement, they are rude and try to change the subject to when I can pay the full amount. It is very unfair that pensioners are being treated this way.
