Amity University — MBA schedule was not truly disclosed

Hi,

I was looking to register for an MBA online course on weekends. Amity online contacted me and told me classes will be held on weekends and I can do it from there. Now after paying the fee they are asking me to watch recorded lectures as classes are being held on weekdays.
They are not responding to my calls after asking for refund. I feel totally helpless now. Please help me.
