Samsun Poor Service

I called Samsung with regards to a TV of mine that had a dark shadow on the screen around mid July. I spoke to a consultant who assisted me with troubleshooting and advised that I need to carry my 65” TV to the Mariri Trading/ PTA Appliances, this agent did offer to book the TV in with the service centre. The TV was eventually fixed and we collected it on the 11th of September, by the 13th of September the dark shadow appeared again on the screen, and by the 18th of September we took it back to the service centre. It is now the 3rd of October, and we’re unable to reach Mariri as we have not heard from them since the TV was sent back. When we contact Samsung, the advise the they cannot intervene as we have not booked through them and therefore we need to contact the service centre directly. I believe that their Service Tracking department should be of more assistance when comes to such complaints and also the agent who assisted me should have assisted me with the option to book the TV I’m on my behalf.
