Accounts department still has not fixed their own mistake after admitting they made one

On the 1st of April I submitted a claim. I received a reply on the 4th and realised it was captured incorrectly. The amount on the acknowledgement email was was for far more than I had claimed - along with the invoice I sent my POP which - and some of the charges I had already been reimbursed for. I called Bonitas on the 8th to alert them to this fact and was assured it was a system fault. Apparently the system automatically captures past amounts and new items if it's on the same document. I was told it would be captured correctly by the right department. On the 9th I received an email to say it was rejected. Still, for the wrong amount. I called again on the 10th to find out what was going on. The claim had not even been captured on my online profile! I was assured the error would be fixed and all would be well. By the 16th, it had still not been captured on my profile. I called again. Again, we will handle it. It is now the 26th. Not only have I not been reimbursed yet, I have received no communication and IT IS STILL not even captured on my profile!!
