4 months in for repair

Took my phone for repair at Samsung Menlyn New World on the 12/07/2017 Order No: ********** 504. No commutation was done in terms of quotation till I went into the store 0n the 26/08/2017 to check on my phone. Only then was I given the quote and declined it and was told the phone will be sent back from the Grove Service Centre till today my phone is still there. I called the Menlyn store and spoke to SK and he escalated the matter via email which none of the addressed people acknowledged. Now I am being ignored when I do follow ups via email.
