Dollar Car Rental - Boston Logan International Airport - BOS - Massachusetts - USA

Be careful when renting a car from Dollar rental car at Boston Logan. I had a reservation booked in advance about 8 weeks ago. Get in Tuesday 6/14 to pick up and was told it had to be back at 7am, but since I didn't get it till 915ish it didn't have to back till that time on 6/17/16. I explained that I had reserved it to be returned at 12-1230 or so. The guy said I had to be charged another full day, even though it was only a few hours difference. I tried to talk with him but it didn't matter at all. He then explained that I needed to get the express pass for tolls because of driving a lot we would need it. I asked how frequent the tolls were and he said all over the place. I had to pay $12 a day for the toll pass. The total tolls we incurred was less than $8.00 total. DO NOT pay for the express pass no matter how much they try to up-sale it. We drove all over Massachusetts and Rhode Island and again only totaled about $8 in fees and it cost me $50 for the 4 days. What a racket they have going there, wouldn't give me a couple hours leeway and charged for me a toll pass that wasn't necessary. My $187 rental quickly turned into $310 because of the extra charges. Anyone else have issues with dollar?
