Last December I called to change my debit date to the 15th only to find that you don't even have my banking details and that I haven't been charged since I started with you. I gave my banking details and also paid a huge amount of money. I recently received emails that my bill is sky high and that you don't have my banking details. What exactly is happening there? I am now told that I need to pay a massive amount of money and all due to your negligence..... I've been sending emails back and forth to a lady named Judy but Judy has now gone silent.... you are unorganized and I now have to pay huge amounts of money because you cant do your work properly
