Same stew different days

OMG, don't even know where to start, long story short ever since I joined the scheme nothing positive has came out of any claims that I made, it's always my invoice is not clear, which now I feel that the message is automated as I have never received a different response except the one I've mentioned. Was told to resend and they look into it and I should everything I have sent previously but yet again same message. I'm very disappointed.
