*****ing money from customers

Discovery seems to be making too many mistakes these days requesting information and confirming receipt and today I have more than double the premium deducted from my account.why ?Who does this and why would you deduct R2249 for a medical aid which cost R1088?this is ***** and you are *****ing this is not an authorized debit. I want my money returned today...I will not be waiting 7days ...discovery is conveniently not available to take calls once their debit order runs so you have 2 options I contact my bank to reverse the debit order and you pay all costs involved and run the debit order for the correct amount or give me my money back.pathethic service yet again ..
