Rude Consultant and unfair billing

I am disgusted to say the least with the rude service from the accounts department at this institution. I chose payment Cash option A and made it clear that the payment will be made by my employer in three months time. The person assisting me at that understood but barley after a month another agent rude agent by name of Shirly decided to increase my fees and not taking into account previous communications. These people call you even during your test week and you have to explain the same thing. I should have investigated more about this institution before I enrolled, it is like they are running a ****. They don't have curtesy and do not accept that not all of us can just pay that amount of money right away.

I am suppose to be studying but I am writing reviews because they are phoning me on during my test week. Stress Stress Stress!

If anyone can assist me with this problem who experienced this can email me ***
