Extremely terrible and uninformative service!!!

On the morning of 19/09/2017 I woke up and my Samsung galaxy S8 smartphone, which I had taken out on contract on 03/05/2017, told me that there was water in the charger/USB port. Surprisingly because I have never dropped the phone in water. Anyway I took the phone to Vodacom at Mall of the South and they told me to take it to the Samsung store in that centre as it is a fault with the phone because it is supposed to be water proof. I took the phone in and a very uninterested employee eventually came to help me. I told him what the issue was and he looked at me and said "Ya you must just book the phone in for 2 - 3 weeks, maybe longer." This is what I did. On the 22/09/2017 I received an sms with my job number, JC143974, from the Samsung Smart Care Centre. On the 12/10/2017, more than 3 weeks after I handed my phone in I had still not heard from Samsung. I the phoned the Samsung store at Mall of the South and they told me they do not have the phone and I should call the Samsung Smart Care Centre in Contantia Park. I tried to call them 4 times and there was no response. Eventually I phoned and got through to someone at Samsung SA on 0 ********** . I spoke to a consultant for 14 minutes and 35 seconds. He said that my phone had been repaired at *** Cellular in Boksburg and is now back at Contantia Park. I then asked if I am supposed to go and pick up the phone or if it will be delivered back to Samsung at Mall of the South, where I handed it in. He proceeded to tell me that he will keep in touch with me, either via sms or a phone call, to let me know what exactly is happening. He never did! Today on 17/10/2017, now 4 weeks since I handed my phone is, I phoned Samsung SA again to find out what is happening with my phone. After a 26 MINUTE LONG PHONE call with a consultant I was told again that my phone had been repaired by *** Cellular on the 28/09/2017 and is now in Constantia Park, which is closed until further notice. Not once did I receive an sms/phone call/e-mail informing me what was going on. I am utterly disgusted with the service I have received from the beginning. I do not know where I stand now or when I am going to be receiving my phone back. No one can give me an answer and no one responds when they said they would keep me updated. I have had Samsung for 4 years now and this WILL BE the last one I have. Thank you Samsung.
