Date of claim payment keeps changing

I lodged a claim for medical expenses incurred last week On Monday 02/11 and was told I'd be paid in 48hrs, it changed to 5th! Today I am sitting at home as I do not have money to travel to work thanks to this poor service. The money should be in my ****** account as we speak. Called in yesterday amd was told the money was release on the 3rd already but even now nothing has come through! Hugely disappointed!
