My Norton Account was hacked and bank account wiped out

On November 6 I received an email telling me my Norton needed to be renewed for $387.xx and that was too expensive for me so I decided to cancel. I Bing'ed Norton and got a number to call and I called them. I told Norton I was going to cancel and after short discussion I saw a AI mouse go into my system and start to uninstall my Norton. We talked about it a little and I told them they should tell me they are going to use an AI so I wouldn't be surprised. They continued to uninstall and then they asked me if I wanted a refund of $350.00 and I said yes and then after a few minutes they said to check my account to make sure the refund went through. I opened my bank account and saw that a refund of $3500.00 was there and said there was an error. The next thing I knew the AI showed up in my bank account and it went to $0.00. I asked what was going on and my voice raised and they told me I typed in an error of the refund. I told Norton that I did not type in anything and they began to argue that I did. They pulled up on my screen the coding and asked me to correct the amount C: and I tried but it wouldn't work. They kept arguing and by that time my husband, hearing all this called the bank, they saw $0.00 and put a hold on our account. Also, I was done arguing and hung up on them. I have tried for a week to get ahold of Norton to get this straightened out and I do not find anything for help. The bank said to scrub my computer ( just unplugged it because it has pictures of our daughter who died of COVID a year ago) So now I do not have my desktop, no help, no refund and probably Norton is still trying to keep us active, except today I received another email from Norton saying my subscription is due for another $3XX.XX. How do I contact someone at Norton to get this resolved do they have a Customer Service number? They are on auto pay from my bank and I want to stop the payments.
