Byju's — No respect for customer, worst consumer support

I want to cancel my byjus premium subscription before my trial period ends, it's 14 th day today and no support has been received, everytime I call their consumer support they keep me wait, now they just play the tune, moreover they cut the call in between. Even I have recorded the calls.
I want to cancel my plans asap, I will not pay any amount if my trial period goes over
