I kept my Tata Zest bearing number MN01S7804 Chasis number. MAT623226ELK25945 for repair at Tiddim Motors, Imphal, Manipur March, 2016. I have called them up for several times whether or not it is repaired/finished. Sometime, they didn't pick up/refuse to response my phone called, until now they have not completed repairing, it is now already 23, January, 2017 which is about 11 months. Kindly help.
Yours faithfully,
Prof. Lal Dena
