Public Storage Unreasonable rate hike and awful telephone customer service Colorado

We have had a storage unit with Public Storage for 14 years. This month I get a notice that our rent is going up from $60 a month to $87.  I called the local agent, Julie, who said they don't have anything to do with it. Then I wait online for over 10 minutes to finally get a real person (Roberta) who tries to tell me that is only a 30% increase and because I can't remember the last 4 digits of my drivers's license from 14 years ago she really can't help me ( sorry 27/60= 45% increase over the $60!) and I should be happy about it being so low. We will be finding a better and more customer friendly spot ASAP.  I expected an increase, but if you received a 45% increase with any other bill, you'd look elsewhere, too. Too bad they didn't care about keeping a long time, consistently paying customer.
