mindwagon sustainable design - wrong information shared while product selling

Byjus claims on purchase that they cater to entire syllabus for standard *-* all subjects as per cbse, icse or state board. this was confirmed several times and on mail by representative trying to sell the product. But only after signing up we get to know only maths and science is covered for class *. So we are asked to pay Rs.***** for * years, promising all subjects but after paying we get to know all subjects are not covered. this is a scam. and people buying product should be made aware of this selling strategy.
