Repeated attempts to get my incorrect miles sorted

Your reference number is: *** <br> Your new reference number is ***.<br> Your reference number is: ***<br> <br> Impossible to get my issue sorted. I have heard your issue will be attended to within 3 working days one time too many. Absolutely shocking service.<br> <br> My medical aid was cancelled without notice on the 8th of November after being with them for 5 years, so after numerous calls I got it reinstated, don't know why I just left. Being on diamond my November miles should be calculated on a 10x multiplier, so after they cancelled my medical aid they calculated it as a blue member so I mailed them to correct, they did acknowledge that it was calculated wrongly but after numerous emails and promises after 5 weeks it's still not corrected. Very bad service.
