BAD SERVICE!!!

In October 2014 I reported that my fridge is not working. After numerous telephone calls and reporting bad service Mastercare's technicians repaired the fridge. On the 21st of January 2015 same problem with my fridge, The technician informed me that the first techisians installed a second hand compressor that is way my fridge was just working for 2months. I called Mastercare again and they send another technician. They took my fridge and it is now the 5th of February 2015 almost 3 weeks and nothing is done to repair my fridge. When I phone Mastercare they just say that they wait for the compressor. It is now going for the 3rd week and it is unacceptable. Poor and bad service!!!!
