VERY poor service

I called more than a week ago to claim my adh repair on my samsung S6 - I was told my phone that my phone would be collected and a loan phone would be supp**** 2 days later (that would've been last week Wednesday). By Friday I had not received any communication from them and my phone had not been collected. They then said they were waiting for loan devices and that my phone would be collected with a loan device to replace it on Monday, but that a supervisor would call me to deal with my complaint about the lack of communication from Samsung - no one ever called.<br> <br> Yesterday, the Tuesday after I was meant to receive my loan device, I received a call saying the courier can't find my address so delivery would only take place today - WEDNESDAY a week and a half later. Delivery took place, but they sent me a VODACOM NETWORK LOCKED DEVICE, after I specifically stated I am with CELLC!! And the soonest they can assist me is tomorrow.....<br> <br> I use my phone for business and I am losing business each day my phone is down! Now it's another day due to nothing short of incompetence!!! I am terribly frustrated! Samsung has disappointed me beyond words, and I've always been a loyal customer...
