There are people online talking about it when seeking to open a new card. I know it happens at Lowes.
You might find it interesting that Synchrony Bank somehow has an A+ rating from the Better Business Bureau, in spite of very negative customer reviews https://www.bbb.org/us/oh/kettering/profile/credit-cards-and-plans/synchrony-0322-5001136/customer-reviews BBB says “Customer Reviews are not used in the calculation of BBB Rating”. So what do they use? https://www.bbb.org/overview-of-bbb-ratings Perhaps a BBB complaint may help you get your $700 back?
Incredible that any business still has relationships with them. I was fraudulently charged thousands of dollars after calling to simply deactivate my card. The customer service agent was embarrassed and claimed that was an error but the card had never been used at Lowes or anywhere and these scrammy bs/negative transactions is why they keep getting sued for unlawful debt collection.
