TTS Port Elizabeth

I took my Samsung Galaxy Note Pro 12.2 in to TTS Port Elizabeth on the 6th of November with a cracked screen and a supposedly faulty battery for repair. I was then given a quote of R6,000.00 which i paid. More than a month later i still haven't received my tablet or any feedback as to the status of this repair. This is the worst service i have ever received in my life. I've called so many times and they always say they'll call me back with feedback - which never happens. Whenever i call and ask for the manager she's too busy to take my call and I don't receive a call back. Samsung is seriously a day away from losing a customer for life. This is just appalling service, is this what Samsung stands for?
