Where Is My Tablet?

I booked my Samsung Tab 3 in on the 28th of March at the Samsung Smart Care Centre in Constantia. I was called three days later to be told that the unit was still awaiting assessment. An entire month passed and still no word on the repairs. On the 28th of April I received a call from a representative asking if I was happy with the repairs done, yet I had no repairs done and I still do not have the tablet. I complained about this on Twitter and I was given an email address to email my complaint and job number. The email has not received a response. I still do not have a tablet. It has been such an inconvenience and the entire thing is becoming ridiculous.
