let down after let down !

STILL WAITING FOR ANY TYPE OF RESPONSE. They tried to call me once - i advised them to please call me after work . no call! ......I am exceptionally and continuously disappointed with how Discovery follows through on their policies and procceedures. Icm one step away from moving to a different insurance company last year i was fully covered for my nose op. due to work reasons i had to push the op back to this year 2019 . Now they are requesting all other reports and scans, I feel they are doing this as i upgraded my plan in december 2018 May I enquire as to how all this was approved 6 months ago but now there seems to be an issue? Nothing has changed and the op required is still the same one - this is slightly confusing to me and to be honest a little frustrating. I have the approval letter stating all was covered from last years- so what has changed in that time??. This is not an operation I am choosing to have but one that is required in order to correct my breathing due to trauma to my nose . I have seemed to be constantly disappointed by the way Discovery conducts their procedures and policies. I pay over R 2000 every month and i am starting to feel as though i am honestly being ****** and that you chop and change your mind on a dime on what is covered . I would not be so frustrated if as you can see this was not all already approved last year - yet now there seems to be an issue.I really would like clarity on how this is possible? AS mentioned how can something be approved 6 month ago and then all of a sudden you are not so sure . Im really disappointed by this and i would really like clarity However before i get overly frustrated i shall await your feedback on the authorisation and all of the above. Should the op not be covered i will gladly leave discovery - who i feel feels nothing for their clients and just wants to keep asking our money look forward to your feedback......posted weeks ago , STILL NO WORD from DISCOVERY
