Monthly Payback Not Paid

I called Dial Direct on 19 April 2021 to raise the issue that I had not been paid my monthly payback bonus for March (as it generally is paid after 10 business days). I was told that the matter was escalated to a manager and that I would be informed of any progress on the issue. I called again on 21 April 2021, to find out any progress and the status of my query still has not been addressed or resolved. No one has called me back or emailed me to notify me of what is going on.

I would appreciate if this matter could be resolved immediately and the monthly payback earned be paid into my bank account.
