YSK: Only make a chargeback when you're 100% sure you don't want to use that business again.
Why YSK: It is generally company policy for many businesses to ban/permanently suspend customers who make chargeback requests with their bank. Only make chargebacks when you're \*absolutely sure\* that you will never use that business again, either for straight up fraud or for refusing to help you in any way for previous refund requests. Otherwise, just submit a refund or fraudulent purchase request with them. #education
