2 months and still waiting

More than two months ago(it was on the 8th of April to be exact), I went to book inn my Samsung 7 inch Tablet for repairs at the Telkom Direct store in Centurion as it was not charging. I was informed it would take 21 days to have it repaired. However, after 2 months of waiting and probably going to the branch more than ten times as I work in the same mall, I am still awaiting the return of my tablet. Every time I go into the branch, all I get is different stories from the technical service desk where it was booked inn and where I am supposed to collect it. You can understand that I have been more than patient with this matter but I have reached a stage where I am going to ring somebodies neck the next time I go in and get told another lie or excuse for that matter. Countless emails have been sent between the agents and with the repairs centre and I still do not see a way forward or any hope of my device that I am paying for being returned. I am utterly disgusted by the level of service and from sitting in their long queues during my lunch or tea breaks. I do not want to hear another SORRY from the agents and I really want my Tablet back right now...I do not care what it takes.
