does the word responsibility mean anything.

It is with great regret that I will have to resort to this. I always believed in your brand .unfortunately your after care services and communication is atrocious. Being a manager and worked for retail just made me realise how employee's lets the company down. I have spoken to your call centre guys who are amazing.Tandi tried to help me and promised me she will send a tech out . To date no one has come. I have purchased a refrigerator on the 9/7/2010. Repaired the evaporator on ***. Repaired on the 10/8/2012. Replaced evaporator cover on 1/3/2013. I have logged a call on the 25/ 8/ 2015 with the same issue to date the issue has not been resolved. Does it take 5 month's to resolve a query. Reference no ***. What is so disappointing there was no return calls or email letting me know what is going on . I had made all telephone calls but to no avail. Why have a voc department if no one is prepared to help with issues???. This refrigerator could be a defective unit . I cant understand why it was not replaced on the second or third time of repair.
