Terrible service

I have been dealing with this people for the longest time. Not helpful at all, I sent my forms in December 2023 and still waiting. It's almost 6 months waiting, they said my forms have been sent to the administrator but when I've called numerous times trying to query about my claim all I get is I'll call u back and they don't. I was then corresponding with someone from the call center which I was then told they haven't recieved my forms from the data factory, so I then emailed my forms through again and then was asked to send a latest bank statement as nw the one I had sent with my forms had nw expired, 3 weeks later no response the person that was helping me at the call center is also no longer responding. On the self help page to track progress says it takes up to 3 months yet I'm already almost at 6 months waiting with no help, all these call centers are not trained very well as they don't know what they are doing, you get no help from them at all. I'm extremely frustrated as this takes up alot of time emailing, using so much of airtime just to call everytime and not to be helped and money spent to email paperwork and now to keep sending bank statements, all this is not free, it's becoming quite an expense dealing with all these people
