SAMSUNG EXTREMELY *********** REPAIRS

I took my my SAMSUNG TABLET in for repairs on the 3rd of December 2014 and was told it would take only 2 weeks. When returning after 2 weeks to collecting I was told that it has not yet returned and will be doing so soon. I returned on the 6th of January 2015 and again I was told that the haven't received my tablet and are expecting a batch of repaired devices later that week. This happened for the next 3 times that I went to enquire about the TABLET after which I requested the number for the EDENVALE office. The first time I called the Edevale office they were unable to put me in touch with the repairs department and told me that they will have the said department call me back. This did not happen. When calling back the second time and talking to the repairs department I was told that they were experiencing difficulties with the repair. I then let them know that it is understandable but unacceptable as no one has called to inform me about the status of the tablet for more than 2 months. I was told that the manager will call me and discuss the progress of the repair.This did not happen. I called them another 2 times and was told the same thing and again the failed to contact me.
