State Bank Of India [SBI] — dishonoring the cheque in non cts clearing

Address:

Central bank of India tandon plaza indra chowk, Civil lines, Budaun, Uttar Pradesh, 243601

The cheque was dishonored without valid reason in non cts clearing (Alterations require drawers authentication) where the alteration is properly authenticated by customer's full signature. When i queried about the same, there officer and clerk replied this is sbi, and we don't cleared this cheque. Acc to ni act this is totally wrong. The behavior of officer is very rude too.
