Imarticus Learning — Regarding Refund of Fee Paid for PGCPECFO

I have paid fees for PGCPECFO programme by IIM Indore through IMARTICUS Learning. While applying for the programme I was told that the classes will be conducted on Sundays however during academic orientation, the faculties confirmed that the classes will be only on Saturdays. I have already informed IMARTICUS representatives about Saturdays being working days for me and have asked them to cancel my enrolment and refund the fees but now no one is responding. Even emails are not replied by them.
This is highly unprofessional behaviour of IMARTICUS team.
