Lido Learning - Delay in Refund

I subscribed LIDO learning for my * yr old son in **/*/**** and after going through the demo class we chose to opt out the lido class because of their poor curriculum and teaching standard. But once we asked about refund then our mental stigma got started and despite multiple followups i did not get any response from their email id and contact number. Its almost * months as against the committed timelines of ** days of refund , i am still waiting for my refund. They are not providing any good intention of refunding my money.
