Corporation Bank — freezing account

Address:

574219

I hold nri and nro account in corporation bank thumbe (1088) branch. From september 16, 2017 my nro account started facing transaction problem then after few days my nri account also started facing same problem. When i check my account status online, it shows balance in both accounts. But i could not make any transaction using net banking. And even it is showing insufficient balance when account is checked using atm. Despite of several complaint via email and verbally to the branch and it's web center no action has been taken yet. It's almost completing one month, this is the worst service i have ever faced and facing. Branch and bank is cheating its customers with false promises.
