Pathetic Service from all departments involved!

For months I have been trying to get Lancet to sort out their claim issues! They keep sms'ng and emailing me for the outstanding funds yet they claiming from my medical incorrectly! The service date of the incident was on 29 Nov 2023 when patient was in hospital. Your accounts or dept responsible keeps submitting the claim for the 30th Nov which is incorrect! I have called in numerous times and sent multiple emails instructing that the claim must be submitted for the 29th which is the date of the service and when your relevant department resubmits they again submit it for the 30th!!!!!!! which is not the correct date. I am not sure who or how I can get this across to you guys!!!! STOP SUBMITTING IT FOR THE WRONG DATE!!!!
