Summit Car Hire disgusting *****, not honoring contract

Very, very, bad service and no communication, do not rent vehicle with Summit! They do not honor their contract, they do not pay the deposit after 21 working days as stated in the contract. When you try and speak to the owner he is not interested in speaking to you as the client, no one is allowed providing clients with his number. The accounts department are conveniently offsite, you leave messages to find out when payment will be made, no response absolutely nothing!! When I rented the first vehicle they subtracted a huge amount and no email was sent as requested questioning what was subtracted from deposit (1 year ago) Very ***** something is not right at Summit, when a owner of a company does not want to talk to a client, it is usually that the company does not have the money to pay the client's deposit. Not trust worthy they should be audited.
