Byju's — Frequently unnecessary call

They call me regularly in 2 to 3 days gap . I have strictly told them not to call and they said you have to clear your child name and i follow all the process they told me even after that they start calling again and again . But this time they take it vary far they call in at 9:40 pm i never received a call from any company after 8 pm . They are distributing my sleep routine as well as other .
