Dreadful, Appalling Service from Platinum Warranty and still left with a Defective Device

I purchased an HP I3 Laptop from Vodacom in November 2018. On the 22 July 2019, the device had to be booked in as it suddenly kept shutting down and then restarted by itself. 1st Contact was first made with Platinum Warranty on the 22 July 2019, a telephonic remedy was logged and a consultant helped with the query by providing self help steps to follow. I was then advised to test the unit and advise. The problem persisted with the same error being received more frequently. 2nd Contact was made with Platinum Warranty on the 24 July 2019 and arrangements were made to have it booked in for testing. The Laptop was returned on the 02 Aug 2019, after all tests ran clear, an update given that all testing done, no fault detected and I was once again requested to test and advise.

3rd Contact: 06 August 2019- I called Platinum Warranty and advised that the device was tested and the problem still persists. I was informed that an on-site technician will be sent and testing will be done- this took place on the 07 August 2019- once again I was advised to test and advise.

4th Contact: 15 August 2019- A telephonic call was done with Platinum Warranty to report the SAME problem that is still not being resolved. I was once again informed that the unit needs to be booked in AGAIN to be "thoroughly" tested. I escalated this matter to management as no Proper feedback/updates and a solution could be given after numerous attempts to having the laptop booked in and having gone through on-site fixing.

5th Contact: 26 August 2019- device was received, the root of the problem could not be detected but a few features were changed in an effort to prevent the problem. I further was advised that a replacement unit can only be given after the device has been checked and tested 3 times

My Experience with Platinum Warranty Desk and the Courtier company used: Courier IT has been nothing but Dreadful! All interactions with them were dissatisfying and infuriating. They lack simple communication s****s and fail dismally to provide any customer service.

I now face a problem which they cannot detect, a defective Laptop and the frustration of testing this device for the 4th time!
