Instacart complaint: Fraud unsolved problem

I noticed a new address appeared on my account…(black arrow) cannot be removed. or changed…called support…did not take it serious, they said wait 48 to 72 hours it would be corrected…this is under my cc info my name, my account, my address…so I kept talking to support…finally the zen desk got me…still no help…finally the person said to close my account and reopen with a new email, did that, still the address came up…could not change, removed cc info, still not solved…finally ran out of emails to add new accounts …my daughter checked her account, same thing,.. I think it happens to be associated with the address….so I will no longer use INSTACART, this is not the first thing…someone signed up for the Express under my account and it took almost 3 months to get them to quit billing me….even with my cc and me doing everything to contact company, they said did not show me getting charged, but my cc sure got charged…until we disputed, I finally got it off and a credit…There is so much room for fraud, don’t care about the encryption stuff, the security is not there, when someone can just lala add a address to an account and it cannot be removed! What to do…DO NOT USE THE INSTACART! THAT IS THE SOLUTON…..
