Poor services

This has not been the first time that I have made contact with lancet with regards to an invoice to send to my medical aid. In fact I contacted the call center on the 3/06/2020&10/6/20 and unfortunately i did not get the consultants name of the first call,but the second call I made I talked to a consultant named Anna and she assisted me and said she will email me my invoices and today it's been almost two weeks and no email had been received and this is exactly what happened on the 3/6/2020 as well. When asked for an invoice on site to email to the medical aid a invoice with no ICD-10 code or tarrif code was given to me. This is very bad service and in future i will think twice to make use of Lancet again.
