Maternity benefit

I thought about leaving it as I thought it is futile but I refuse to. I complained about it on hello Peter got a few calls still nothing was resolved to my satisfaction I then received a call from Lorraine who said it is a typo error and it will only be fixed next year and that some woman go to GPS till the end how does a typo error in your brochure, portal as well as maternity letter become my problem your brochure, portal and letter all says the same time but upon registration we get told that is not what we will be receiving imagine and yet the excuse is it is a typo error yet no retraction letter or anything was sent to members all you get is when you register is a helluva surprise I demand to get what is on your brochure, portal and letter. I have sent an email it's been over two weeks still no response and they forever saying they will escalate
