Discovery keeps loosing my claim

I submitted a claim for my 1 year old sons vaccinations in February.

In May i Followed up and was told it fell through a gap on their side and was not processed. They apologies and resubmitted on my behalf while on the call. They called me a week later to apologise and say they had nit loaded it correctly and they have corrected their mistake and it will be paid in full the following week. I followed up the following week with the latest reference number provided and the assigned consultant could also not provide any clarity

I have submitted all my baby’s vaccinations without any problem and the claim is always paid in a matter of days

I have tried to escalate this query as it is starting to feel like Discovery keep delaying payment in hopes that I forget about it. There is no other appropriate reason as to why the claim is not processed and no one can produced me with factual feedback
