Mismatch in interest earned and shown in form16a

It is found that the amount of interest earned upon FDs (Shown in Interest Certificate) and the amount reflected in Form 16A mismatches. Form 16A is showing lesser amount. However Tax deducted amount is shown correct.

In such case, What we have to do?

Do we have to pick the value from Form 16A or from the interest certificate. Bank says that they usually round off the value to nearest 10s (e.g. if interest earned is 1104.00 they show in Form 16A as 1100.00).
