New PC defective

If I read some other complaints, this branch seems well known for bad service and excuses for not having keeping their promises. I took my brand new tablet with defective keypad to fix or swap the keypad as it is not possible to use it on 6 June 2015, driving specially from Caledon to Montagu gardens. I was promised after they established it is not repairable that they will have the part with them on 22 June 2015, whereafter they will courier it to me. The date came and pass and it now reach a point where they don't have a clue when I will get my tablet back. Even telling this person that I will report he poor service to Helo Peter, he did not even attempt to indicate when I will get my tablet. Further, I reported them at SAMSUNG head office and that even is not bringing the matter to closure. I always thought SAMSUNG is the way to go, but with this experience I will surely not promote this brand. It seems I will wait and that is how it will play out. Wander if I can lay a charge at the SAPS for taking my tablet with the intention to fix it and now the keep it.
