PharmEasy — Change in policy and No reply at all from them

I took pharmeasy franchise 2 months ago and we were getting 15-30 orders per day as promised. Few days ago the policy was changed and now we are getting only 1-2 orders a day and sometimes even no order online. This is direct breach in contract because they have stated clearly that before making any changes they will discuss with us and then do it but no discussion took place. Our manager ( Ilyas Sabad) no longer picks up our call and has even blocked my number. On contacting him via whatsapp he leaves the message read and doesn't reply. We have mailed several times but have got no reply at all. We are now left in dark since we don't know where to go now. Our business is going into loss due to no orders. Please help us getting our voice reached to them.
