Fraud faced by bangalore locals, outsiders,
Fraud experience : with elite business services, no.1311, second floor, 25th main, jayanagar 9th block, bangalore-56069,
I had got a call from ms. Meena/ arshiya from mobile no.[protected] & darshan/ irfan [protected] for an interview at jayanagar 9th block, once the interview was done, they said i have been selected for flipkart - crm process, to provide offer letter they asked to pay rs.5000/-. Then ms. Arshiya gave a offer letter which is very unprofessional and provided a receipt which is also unprofessional.
I had to resign from the previous job believing them that i shall be joining flipkart, i have been trying to reach them before the joining date to check the address of flipkart. But their numbers were un answered.
On joining date i realise their mobile numbers are switched off. With the intention of fraud this is happened.
Later i visited to their office in jaynagar to check if they are available their. When i reach the office is close and the whole building is locked.
We tried to reach them several times but they are not contactable, sometimes these numbers rings and later they will switch off their phones.

Please pls candidates don's ever believe them or any consultancy here afters.
