Calling lots and lots today. Fortunately NOT collections calls, although those are going to have to be done again soon. No - the company is switching banks, and I have to call EVEYBODY who auto-deducts and giving them new bank info - or getting forms to fill out to give them new bank info.
The first lady I spoke with started to freak out when I began to ask her about how to change the account information. I think she was afraid that I had some complaint and wanted to cancel it, or that they'd deducted multiple times or something. She was all flustered and cutting me off before I could finish my sentance - so I waited a bit then told her "whoah! Hang on! We LIKE the service - but we'd like to continue it and if you don't let me change bank accounts, this one will be gone and you'll not get paid!" Then she calmed down and we got it all straight.
After that, I started to preface my "attack" with "You take the money directly from our account and WE LIKE IT A LOT!!!" I got laughed at a lot, but at least I didn't have any more customer service reps having a stroke trying to anticipate negative interactions!
