Simplilearn — Course Refund-Scam

Is this a scam, I thought i was dealing with a reputed organization when i enrolled for the course. Their approach while canvasing for the enrollment was remarkable. Prompt updates, emails and phone calls. But after the process, when I have requested for a refund (within their 7 day policy), they completely ignore emails, whatsapp messages and calls. This is very disappointing. I have paid more than i would have paid other course providers under the impression that it will be worth it. Honestly when i decided that this training was not for me, i thought i would use them for other easier courses . However the experience has been very very disappointing that I would never come come back to them nor would i recommend them to any of my contacts. It is sad that such scams can run in the name of education
