Unhappy customer service

I bought a Hisense washing machine online and the 3rd September i received it. On he 6th September i called to log a service. I was told I would receive a call. On the 8th I called again and gave my details and even made a complaint online and still nothing. Today 17 Sept all there lines where busy so I logged a call to Hisense myself. The customer service is pathetic as I could not use my washing for a long time and now I have to wait to have it fixed as it could have been done long te ago
