Continous Harassment

Autopage believe that they have a right to harass the customer. What they say goes and when they are wrong they offer no apology. I have been continuously harassed for paying my accounts on the 25th (or few days later) which is my salary date, they insist I must pay on the 15th. Every month I am harassed for that. Secondly, I made a payment which they allocated wrongly and got harassed because \I did not pay"";also to ensure that they fix this mess because it affected my credit score"""
