Client Service and Customer Care/Aftercare

I am absolutely disguisted by how Part Masters decides to handle their customers, At first I struggled just to get someone on the line who will be able to assist me with my problem, once I get someone who sounds like they would help they transfer me straight to voicemail, I decided to leave a message for them to phone me back where I was told she is probably not phone me back. After that I was told to wait the 2-4 Days it takes for the testing "Monday at the latest" she said. On Tuesday 5 Days later i try to phone again getting transferred to voicemails etc...finally upon sending a mail where i request a reason for why my credit took so long and asking why the customer care is not really good at the moment I was met with a email reading Hi please find attached your credit note. Do you guys honestly not care about customer service ? this was from a manager btw.

No apology, no accountability, nothing Please get to fixing this problem your pricing is awesome it just seems like you dont really want to sell your product...
