Authorization given, then payment refused !!!!!

Good day<br> <br> Following a stroke late last year, complicated by Arthritis, I was advised to have botox in my leg as it was the last hope to fix my leg so I can walk again.<br> <br> Discovery authorised the botox, from my Keycare Specialist Benefit Limit which had about R2500 available. <br> Then when I claimed back from Discovery they refused to pay !!!!!!<br> <br> The botox cost almost R11000. All I am asking for is the R2500 that Discovery said was available to me.<br> I desperately need that money toward my therapy or else I have wasted R11000 and more then likely will not walk again.<br> <br> Is this how Discovery treats there clients ?????<br> <br> I am disgusted !!!!!
