Phone not being repaired

On 2015-03-21 I took my Samsung S5 phone IMEI nr *** Serial nr RF8F406GH6Y Model S5/SMG900F to Vodacom in Woodlands Pretoria. The Vodacom store requested me to hand to phone in at the Dion Wired at the Samsung Smart Care Centre. <br> <br> Since this 2015-03-21 when I handed in my phone to this Samsung Care Centre I went back to enquire about the phone`s progress 3 times, called the head office once and now wrote a e-mail to Samsung head office. The first two times I went to the store, the consultant informed me that there was no response from their head office yet. The last time the female consultant informed me that she don't know if my phone was missing as they are not getting response from the head office.<br> <br> The phone is missing to date and I am not getting responses<br>
