Planetspark — For providing less number of classes and not reachable

Due to covid -19 the children are to stay inside the home and the schools are also online.
To keep my kig engage I took his admission in online courses for Public Speaking.
The counsellor of Planet Spark promised me to provide 165 classes and i am email as well as proof for the fee payment and classes. But planetspark website is showing only 135 days. I am not able to reach planetspark from last 10+ days.
Moreover phone is not getting picked on customer service number. My son has completed 35 classes. Please help me to get refund for remaining 10 classes as per policy of planetspark (no question asked for refund request).
