Very misbehaving staff I've seen, NOT AT ALL RECOMMENDED

Worst app & staff I've seen in my life Today at 9AM while I was attending meeting I got 3 calls in 1mins, I got scared & had to hold on my imp. meeting to see if there was some urgency, but she was this Shalini Verma acc to her and Shaifali Verma on truecaller, from testbook When I ask her to pls mind & not call anyone so frequently, instead of feeling sorry she started arguing with me like hell. You can imagine if they're misbehaving like so in the 1st talk, how'll they treat after you've paid. And when Testbook is not able to train their own employees (even atleast to talk properly and don't misbehave) how will they train you for any exam because behaviour is the foremost thing than teaching.

NOT AT ALL RECOMMENDED, don't waste your money, when they can't atleast talk properly, how will they teach you, because this is the basic that they can do.
