when i purchased ias bhlp course for **** one person name Mayank Mahajan called me and give me the deatils. He told me that byjus will give you updated tablet with all recent topics even during live class doubts will also be cleared on spot & give the details of teacher who teach me in ****-**** entire year. I paid initial amount ****/- and rest will be in instalments. when i received tablet was not updated lot of topics & lectures are missing from the tablet which are more likely releveant form exam point of view for that i called him tell them about tablet but this issue but till date there is no resolution. when it comes to live classes teacher which taught economy was not the same as told by Mayank Mahajan , even doubts were not cleared in class for this i called several times to mayank and even in byjus mentor no. But no resolution . They didn't respond me on call and on mail. At last i put mail and call byjus to refund my money but there is no response till date */*/**. Byjus are trying to ruin my career and due to byjus behaviour towards me for not refunding for not resolving any thing am feeling depressed and even byjus put me in a position to succide. because ruining my dream my career.
