Gatvol previous unhappy customer

This company doesn't take its customers serious,they s.ell lies to you and when it comes to time for first payment you get charged more and that you never agreed to and when you contact them to fix that they do it all they say is we are still investigating until you decide to reverse their debit order and they will add interest so they can milk you money,again they blacklist you and when you write a bad review they come running and contacting you and again they promise you lies that they are still investigating and when you contact them for feedback they ignore your communication until you come write another review that's when the lady called Caroline will contact you and apologize for late response cause they are trying to act holly,again they say you never sent themsuch information to them when you provide proof that they acknowledge the receipt of it they change their story to saying that email was not meant for me but for another customer,they are trying to cover their tracks.Since they promised me that they are investigating 3 weeks back and no one has ever came back with the feedback of their investigations, all they do is sending me invoices with increased amount every month. I ma tired about this this company I am now taking the legal route
