incredible connections not so incredible

I took my Samsung tab 4 fo repair to incredible connections in Worcester on the 13 of September after my charging system was damaged within a month of purchase. Till today its been stories, I have not got my tablet back. I have been calling the shop to follow up on my tab being repaired its stories, this is the 2nd month and im ****ed. That tab is still new now I don't know where it is because im being told to call the complaints \what so ever"matter was taken to their head office bla bla.... I want a new tab I spent R3 000 on that it might not be much but for me it is.... I demand a refund or a brand new tablet I have waiting long enough and I'm exhausted ****ed thought they were professionals. I had faith in these people."""
