State Bank Of India [SBI] — Wrongly cheque returned

I have an account with State Bank Of India. They have offered a MOD facility whereby the amount is transferred from the fixed deposit into the saving account as and when the need arises e.g. clearing a cheque. They call it sweep transfer.
A cheque that I issued to a payee returned unpaid stating insufficient funds. This was a shock to me because I have more than enough funds in MOD FDs to clear the cheque.

When I inquired at another branch the manager raised hands stating that I should contact the base branch. When I contacted the base branch the manager there said that there was no need for cheque dishonor as the funds could anyways have been swept from FDs.

The manager also said that most likely the clearing personnel did not know about the MOD facility and he might have rejected the cheque by looking only at the saving balance. They were not ready to do any further investigation or really try to go to the depth of the matter.

What more can I say?? This is the worst bank in India
