Claims a nightmare !!!

I sent through a claim via email last week and still to this day I still haven't received any feedback and my discovery profile hasn't been updated with the claim so I am unable to track it . Over and above that , I logged a query this morning about this issue and i got an automatic response that I will be contacted within 2-3 days . This is ridiculous as it cannot take this long to process a claim and in addition to that take more days to contact m3 after sending through a complaint .
