PayPal Holdings, Inc. Bank Account Or Service Complaint

PayPal Holdings, Inc. Bank account or service department,

Other bank product/service Account opening, closing, or management Arkansas

I was making a PayPal transaction, and I noticed an ad for a $10.00 dollar discount on my purchase if I signed up for PayPal Credit. I started filling out the form, but I saw that the credit would n't be applied until after my credit report was approved, so I cancelled the process. Later I made another PayPal transaction, and it was charged to my new PayPal Credit account without my knowledge. I paid the balance and explicitly changed the default payment method to my bank account, but my next purchase was charged to the credit account without my knowledge. They now tell me I owe over $90.00 in interest and late fees and interest on a small purchase. I have contacted their customer service department several times, but they have given me nonsensical responses. They continue to call me multiple times a day. I have closed me PayPal Credit account and my regular PayPal account. I 've read that you have fined them last years for just these practices, but they continue. Please help me.
