Discovery service cause trauma and loss

I have been contacting Discovery consultants 2-3 times weekly for the past 2 months to correct errors they have made with an incorrect double claim that was deducted from my savings pocket. I was repeatedly told 'it takes some time' , 'it would definitely be sorted' and in several occasions given apologies that further errors were made in the correction. It has caused me undue distress that almost R6000 was taken from my savings pocket, and has cost me a huge amount of time, effort and expense to try to sort out the matter. It is yet to be resolved after they made yet another error. I will never ever refer Discovery to any person in future.
