Poor services

poor services , i had changed my enigine .. Regassed it and everything was working . my compressor gave up , which was an old compressor and didn't come with the engine . i have spoken to them plenty of times then they askedfor proof of regasing i showed them ,but still ntn ,i have been asking for recordings of calls which they did not give me ,up till today , im upset that they just decline the offer but then ask for proof and when its given to them they find a way to tell you there's ntn they can do.. Still waiting for the recordings !!! Over 3weeks i had to pay for the compressor by myself and will like a refund cause i have got information and the right one..
