Bin There Dump That

I called JC Q4 2015 and told him my situation; 1800 SQ FT, renovation to remove flooring, counters, vanities, some drywall, sinks, toilets and a 100 SQ FT rock wall. 3BR/2.5 BA
He told me the 14 yard dumpster would more than cover what I need. I also had other quotes for about $ 550 with much larger dumpsters and I told him I didn’t want to spend any more than that. I chose them because a friend of a friend recommended them.
I took JC’s expert advice and recommendation since this was a first time for me. Needless to say I went over almost 4 tons in weight and then they had to try and sell me another dumpster when we were already at budget. Blah blah blah. So they charged my credit card again without my consent for their mess up after sending me another dumpster. This gets really bad now because I called and left 2 messages and emails saying I was calling VISA to cancel the 2^nd transaction and nobody ever got back to me still til today. Next they lose the fight with VISA after sending them only there side of things, leaving out all of my communication/​requests. Then they send this to a 3^rd party collection agency after they lost with VISA, in which I will forward all the information VISA had. A customer should not be charged without consent nor should a customer be responsible for an estimate gone wrong. They tried charging me over $ 900 when we agreed to stay under $ 550. I run sales for a company and if I quote someone a wrong price I eat my mistake to make the customer happy. Very disappointing experience overall when a simple phone call back could have saved them time, money and negative reviews.
