Phone booked for repairs still not been collected

<br> Hi<br> <br> I bought a Samsung Tab 4 for R2799.90 at Edgars Wonderpark Mall on the 23/02/2016. This tab stopped charging after 10 days. The charging port was not working properly, I took it to the store to be booked for repairs. The same lady who sold me the phone by the name of Poppy was very helpful and professional. She booked the phone and told me that it will take approximately 6 weeks. I had no problem about that. On Monday the 11th of April I went to check my phone, I was helped by Mantoa who was very friendly and helpful. She told me that my phone was still in the store waiting for collection from Head office cellular department. She called the department and the phone was just ringing for more than 20min. I ended living the store without any concrete answer on when can I come for my fixed phone. This is really a bad service from you guys. All I need is my phone or my money back.<br> <br> Regards<br> Joseph
