STILL NO FEEDBACK AFTER 32 WORKING DAYS

I've never ever experienced such bad service at ANY company before. I'm so frustrated! Why can't something so simple be sorted within the relevant time frame? Upon calling the call centre, week after week, because I do not get any feedback on my TAX return, even though the matter has been escalated and is now taking more than 32 working days. Phoned AGAIN today, spoke to a "team manager", ***nor and now I have been told to wait until something happens: She can't give me an aswer, but I have to know that there is no turn around time, no accountable person to contact, no one knows about the progress of my case, no one willing to try and assist me, NO ONE! No one to contact except the customer service centre where I get case number upon case number, but still nothing happens! What should someone do to get assistance in sorting and getting tax returns? The client service is pathetic!! "I DON"T KNOW" is not an answer, because that is the only "answer" the agents has!
