Same here and I called today.. twice.
Attempt #1 was in the morning and the gentleman at the call centre took the better half of a minute repeatedly asking me for my name and surname. I thought that keying my ID number during the call prompts would improve speed, but nay. Anyway, what I finally got out was that 'yes, those fields are missing' and that 'no, those values aren't filled in any more' (even though they existed in the past). Too bad that when I inquired further, he politely said bye and hung up.
Unsatisfied with the earlier reply, I went for attempt #2 was in the afternoon. This time the lady insisted that my employer had filed the IRP5 incorrectly (even though I had it in front of me) and that either my employer needed to file it again or that I would have to had to refresh the IRP5 data (even though I have done so repeatedly).
I am unhappy with these replies since they don't seem to be backed by any facts. I am not sure if the call centre people weren't trained or did not understand my question (even though the voice prompt insisted queries would ONLY be handled in English). All I wanted was a factual answer to my question: "Why are both fields, Employee and Employer UIF Contribution (4141) and Employer SDL Contribution (4142), missing from my ITR12 even though they appear on the IRP5 given to me, and have in the past?"
Anyone else had better success?
