Metropolitan Life Stinks

I received a sms from Metropolitan on the 7th of December informing me that my debit order will go off on the 15th of December. I immediately phoned Metropolitan to inform them that my salary will only be paid on the 22nd of December. An agent answered my call and explained the situation to him. He kept telling me there is nothing that can be done. Even after telling him that I have 2 debit orders that will bounce and that the bank will charge me, he refused to make a note and then put the phone down while I was still talking to him. Then I send an email and I still haven't heard anything from Metropolitan. How can a company just decide that people will get paid earlier in December and then change the debit order date without consulting their clients. This is unacceptable.
