It is not a cab service application or company like ola or uber. Its a commission based 3rd party company.
They make you pay advance and that advance is around 40 percent of the agreed fare. This advance they never pay to the vendor / driver and you would need to pay full trip payment to the vendor , so you end up paying a lot more than the actual trip cost. Do not pay anything in advance over the link shared by the broomboom representative over watsapp.
Its a scam which I got trapped to but would be happy to save many others who read this review...
