My rating is zero (0). False promises by Simplilearn team to the students.

Did your contract say that you can swap the course at any time or were there any cases where they could end support? For example, if they let you switch if you are continuously doing it but if you disappear half way through and then come back 6 years later and what to change they don't have to support you? I would check your agreement carefully because the rest of your conversations don't really matter unless the agreement is ambiguous or someone modified the agreement through a formal communication based on the rules in the agreement.

Yeah that was me. And even though you see me all over Reddit, I spend very little time here relative to how much I still code :P
