Very bad experience.....

Very bad experience.....
I went linux lab for Redhat course...
Actually i have paid half fees of Rs8000.
After attempting one single class for 2 hour....
i realise that teaching is not good here so i decided not to continue...
When i ask for refund my paid fees of Rs 8000 , they deducted Rs 1500 from Rs 8000 for attempting a single lecture for 2 hour .....
This is not fair......
So think twice before joining this institute ....
They are money minded .....
I will not recognise anyone to join Linux Lab....
