Bank Of India — delay in cheque deposit

Address:

Amravati, Maharashtra, 444605

I had given a cheque of rs 1.14 lac to deposit on 3dec. Cheque is from sbi. I got an msg as money is deposited. But on the same day i got another msg as amount got debited and they apply 590 rs charges due to cheque cancel. I went to bank. Manager told us like we missed to attach the cheque that's why it got cancelled, no need to worry it will get deposited in next day. After that we visited the branch for next 4 days. But on 5 th day manager returns the check & he mentioned that sbi has some internet issue, so they are not accepting this cheque and he returned our cheque. Is that really a reason??
