I have never had a problem with Wells Fargo, either in person or by support via phone. The employees have always been understanding of my concerns and addressed them quickly with a polite and professional demeanor. I even have a mortgage through them that gave me a great rate with lowest possible closing costs I could find out of about 10 different brokers, it is also incredibly convenient to have my mortgage linked to my bank accounts and see everything with one online login.
I would give them a perfect rating but they kind of need to be watched for monthly maintenance fees suddenly appearing on my statements when the criteria to have the fees seems to change unexpectedly. Of course this has only happened twice in 8 years.
