MTN - Transfer of Data allocated to wrong number but not being reallocated

At the beginning of lock down we organised for one of our staff members who did not have internet to be given a modem and we then paid R900 for data so that he could use the data and continue keeping his work up to date. Unfortunately, the person who up loaded the data put 1 digit incorrectly on the bank when she paid for the data. We have tried for 2 weeks to get MTN to transfer that data to the correct modem. They have refused to assist us. The consequence of this is that this employee will not be being paid as he is unable to work. We are very disappointed in MTN not being able to assist us in this matter. We have moved from pillar to post with the last recorded message stating that it will be refered to the supervisor. We are still waiting for a reply from the technicians.
