Cheque Deposit

I visited the branch on the 03 october 2015.wantee to confirm a cheque deposit that was made in to my account. <br> The lady who was working at inquiry confirmed that transaction will not returned or reverse in one way or another.i made a business deal based on the information I received from the branch.<br> On the 07 October 2015 I received sms notification saying the cheque was returned so when I approach the branch it was word against her and even the branch manager intervene but on her side.i was not happy because I went to the bank for advice and is the same bank that refusing the responsibility and accountability. <br> I need someone to investigate this matter until is resloved and someone need to account
