NIIT — Mis behaviour and direct warning of suspension because of installment issues

Reapected sir/mam,
This is jawaid akhtar here father of mr.mizaan jawaid who is currently taking course in your reputated company NIIT salt lake centre.
First of all i want to inform that the centre is directly giving warning of suspension to my child and knowingly presenting that verbally conversation doesn t mean or proof something this is just because at the time of admission the head was somelse and as he was replaced from that centre my conversation with him too vanished like him from the centre. I know installment has to be paid on time but teacher have to talk to the parents directly and inform them about this and not to the child with a warning my child is a bit sensative if incase he takes up a wrong step i will sharply blame the institution.
NIIT will be responsible for this.
This institute itself is huge and reputated.I hope they need not to fall so much for just a installment infact without completing 20%of the course.
