Shocking admin

Absolutely shocking communication and admin. I have never engaged with such bully's without any interest in customer service. Their Terms and Conditions CLEARLY state that payment is due 21 days before start date however they invoiced me on enrolment. Without any other communications, they sent invoices over and over while I was still trying to find out a suitable start date. There was no comms stating that payment was due before start date was agreed to and then they hand me over to lawyers. I then paid the fee I was quoted and not any 'late payment' as their T&C's clearly state on start date however I now get emails for the late payment. When asked for clarification on why I am being charged late payment, I get told I am looking fort loopholes and I will be handed over. The teacher is amazing however I will not be returning or recommending this place to anyone.
