If your colleague has allotted the same number for two different employees, then one of them will have a wrong account number with respect to that employee, resulting in zero contributions for him. I believe you need to make a fresh contribution with the penalty charges as follows:
- Less than 2 months: 17%
- 2 months but less than 4 months: 22%
- 4 months but less than 6 months: 27%
- 6 months and above: 37%
You have the provision to recover the double contribution made to the same account number under sec. 32(1), which states the recovery of a member's share of contribution:
"Provided further that where no such deduction has been made on account of an accidental mistake or a clerical error, such deduction may, with the written consent of the Inspector, be made from the (Subsequent) wages."
