E today where i lost my cell phone as it was connected with the ox wire in his driver seat, when i asked for my cellphone after paying the bill the driver ran away with the phone. Now he is not even picking my call, he has switch off his number and now he is not even active.
Such a pathetic services from old driver wasnt expected, i even texted him saying if he needed money then i can give him as that phone is very important to me where i have all my business contacts and files, but neither he picked my call nor he is reverting back my sms. This is very tolerance as how can ola hire such cheap people's.
