Shocking, unempathetic service!!!!

Last Thursday I was told that the error made on my tax certificate would be fixed by today. After 5 phone calls and numerous emails I have been told by a very uncaring call centre agent that it is not going to happen. This error has now been made two years running Discovery Invest has made my life this last week hell and nobody cares. Dee Dee at least returns my calls but she's not in a position to help me. Four digits on a tax certificate can't be that difficult or time consuming to change.
