Seven incorrect invoices were sent to me without my approval

I received seven separate invoices for v0 Credits on May 1st, but I only authorized and intended to purchase 30 credits with a single click ( $31.17). Instead, I was charged for 278 credits across 7 invoices totaling approximately $288. I am certain I only clicked once and did not make multiple purchases. Three refunds have already been processed through chat support (invoices UFI6YM8T-0033, UFI6YM8T-0034, UFI6YM8T-0035), but the system has reached its automatic refund limit. I am requesting immediate refunds for the remaining 3 unauthorized invoices: UFI6YM8T-0036 ($43.52 for 42 credits), UFI6YM8T-0037 ($44.55 for 43 credits), and UFI6YM8T-0038 ($42.49 for 41 credits). This appears to be a technical issue or potential unauthorized account activity, and I require urgent assistance to recover the approximately $128 in unauthorized charges still pending.I think you guys have a hacking issue or something because I am %100 sure about what I did

Have you tried going through support for the remaining invoices?
