If you used GoFundMe...
Request a chargeback refund online or by calling Visa, MasterCard, American Express, etc. directly.
My company accepts credit cards...your processing rate goes up if your number of chargebacks increases. You are accessed a fee to process each chargeback. It is a huge pain.
Do not wait for a refund. Use the 800# on the back of your credit card or the link on your mobile app. It is very easy and takes just a few minutes.
GoFundMe needs to be eliminated.
Go-Fu#$-Me need to be charged so many fees that they're mashed like a potato under the weight of debt.
