Bajaj Finance — ECS Mandate rejected

Address:

676104

Hi,
This is wrt Loan #5U90CD22199545. Received a SMS from BH-BAJAJF on 21/06/2016 stating :

ECS mandate has been rejected by your bank. Pls submit a fresh mandate form
and cancelled chq to our branch to regularize future EMI's to avoid any
CIBIL impact.

The product purchased was from UBC, Tirur

Have made many calls from Registered Mobile No. to find out the reason as to why has the ECS mandate been rejected.
But there have been no clear answers.

Please guide me suitably.

Regards,
Usha
