I need my tablet back

I submitted my Galaxy Tablet for repair on the 17th of January 2015. It is almost three weeks and every time I call I am told the same status that the parts have arrived. There is not even a platform to provide me with proper feedback except for the stupid call centre I have to call, with people who just read the status with no clue what it means. I am starting to believe there is not interest in getting my tablet fixed urgently. I need my tablet to conduct my business smoothly and everyday it is not back is frustrating me. I cannot buy another one now because I still have a contract on this one, but for sure will not be buying a Samsung ever.
