Notapaidreview in Vaughan

I have had two storage lockers with Migson Public storage in Toronto, ON since August 2015, no issues until recently with a change in management and staff. My rent on my unit was increased by 70% with no notification, simply a demand of payment was requested up from the regular $279 + taxes to $479 + taxes a month. I called the office, when speaking with Gary (employee at Bertrand location) he explained that it is not his job, he had no time to discuss my billing change with no notification, he suggested I was at fault for this billing change, and that it would have to be 15 years ago for me to be paying $279. Gary came of rude and aggressive over the phone, so I requested to speak with management or an owner. I spoke with Shawn (Management at the Gerrard location), at first he told me I have always been paying $479 that was final, he emailed me an invoice of this (August 2017) month's request of $573, he told me I could have never been paying $279. I emailed back and requested a copy of all my previous invoices. Gary emailed me back my invoices up to December 2016 and the invoices show that I have been paying $279. I requested staff to rectify this billing issue because the rate I am being charged is not the rate agreed upon the contract. Gary calls me back and tells me that management has recently changed and that my rent is going to be $479. I explain that this is not the agreed upon contract rate, and that I have had no notification of this price change. Gary tells me he doesn't have time, he says I have been notified and he is not going to fight with me, so I request to speak with management. I speak with Shawn and he explains that they have being doing me a favor by charging me $279, he kept mentioning a gift horse analogy, and that $479 was a good rate. When asked what kind of notification was sent as to the price increase he simply told me I was notified. My personal feelings about these two individuals I have encountered at Migson Public Storage recently are that they seem dishonest, they're actions and statements poorly represent the company.
