Discovery Life Payments dept are useless!

Discovery (payments dept) got a source code on my tax certificate wrong. They said they would fix it and resubmit my tax certificate which takes 7 - 10 days. I explained that if I don't submit my tax return I won't get my refund and my daughter's place at university will be lost as I can't pay without the refund. They said they would escalate the fix to senior management to get it done quicker. I'm still waiting! I phoned again today and Thabiso told me that still nothing has been done to rectify this. The error is Discovery's fault and now they are not fixing it. 🤬
