Terrible service

I went to Dion Wired at the East Rand Retail Park on the 30th of January 2018 to get my Samsung S7 Edge repaired (my Samsung S7 Edge is still within its first year so the repair is done at no cost). Dion Wired was a recommended store by Samsung South Africa as a repairs store. I called the store prior to bringing the phone in to check how the process works and what I need to bring in. Upon taking the phone and the papers needed to the store I was informed the paper I had was incorrect so I had to source the correct document needed and went back to the store. The gentleman (Lucky) behind the counter assured me that the new document was fine and it would take about 2 and a half hours to repair the phone. He then proceeded to call me and tell me (which I later figured out was a LIE) that the document had to be sent to Samsung as it wasn't what needed to fix the phone and they would only get back to him in 24 hours time. I then managed to find a proof of purchase or the Samsung so I called to ask if I brought the document if it would assist the process of getting the phone fixed quicker only to be told that he had left for the day. The following day (31 January) I went to go give him the document and ask if the phone would be fixed on the same day and he was not at work. I unfortunately work and stay in Pilanesberg so I needed the phone to be repaired that day as the following day (1 February 2018 - today) I would go back to work. The manager proceeded to fetch my phone for me but my phone was already opened and had been taken apart so needless to say OBVIOUSLY the gentleman (Lucky) in fact did NOT need to wait for Samsung to get back to him and he just felt too lazy to finish repairing the phone. He didn't even have the DECENCY to tell me that he is not working on the 31st of January. Now today I call the store and this gentleman is STILL not at work (which BY the way when I was at the store on the 31st the manager "DIDN'T KNOW" if the gentleman would be at work on the 1st of February - I don't understand how you can not know if your staff is rostered to work or not)!!!! So needless to say my Samsung S7 Edge HAS STILL not been repaired and no one can tell me when this gentleman (Lucky) will be at work and will fix my phone. Just to add to this wonderful story I had to purchase a phone as I did not have mine and was relying on having the phone repaired in 2 hours!!!!!!!!!!
