Unprofessional service

Disgusting service , I was auto assessed on the 7th of July it showed I owed SARS money because they didn’t use my medical aid certificate the same thing they did last year , I manually submitted it on the 15th July 21 working day to validate one simple document has now turned into 30 days and nobody can give me a answer as to when it will be attended to , I am highly irritated and want this resolved last year they garnished my salary for the silly fault
