Irefer issue.

I am a miway customer and miway has something called irefer. It states in the terms and conditions "You as the referrer, a Miway client will qualify for a voucher, on a successful premium collection for their policy, which is payable within 30days from the date of successful collection of that premium" . It has now been 32days and I have been reaching out to find out what's happening and was told to wait until yesterday I waited and nothing. Today they said they would escalate it as the times I reached out it was never escalated. Please do then change your terms and conditions in your policy for the voucher if you cannot uphold the terms you have listed. I have brought this on here because I had to call on multiple occasions and reach out and still no assistance.
