Bell Canada. Paid the overdue bill last week, today I get a message that our service is suspended for unpaid bills. Turns out that wife had paid the money against her cellphone account rather than the TV/internet account. I point out that given we are on their One Bill service it shouldn't matter, but no. They have no way of transferring this large amount of credit now sitting on her cellphone account to our TV/internet account, so I had to pay it again in order to get the service back on.
Their contact centre staff are monumentally stupid and unhelpful. I am less than impressed at having to waste an hour of my time on that.
