Any who have suffered a loss also have a duty to mitigate their loss. Today or whenever you became aware of the loss you are now able if you choose - to buy back in. Your loss is the difference in the cost of buying back in on market (from today or whenever you became aware) LESS the credit of the unauthorised sale of your options (credited to your Acc) IMO. The loss is quantifiable now and not some mythical figure into the future. To be honest your loss although a real pain in the rear does not amount to substantial damages etc. The fact that you post here is evidence that you are aware of your loss and the loss is therefore quantifiable. As mentioned you have a duty to mitigate your loss - it does not continue to run into the future. A class action isn’t going to cut it cost wise and the cost would be in excess of your loss. Seek legal advice as no doubt the “fine print” needs to be considered which probably authorises them to sell the options. Lodge a formal complaint asap. (Please note this is not legal advice and DYOR). Sorry for your predicament and these are my thoughts from someone who failed high school.
