Liptronics - Lying *******!!!!

These "Lying *******" were appointed by Samsung to determine why my TV had a "grey shade" over the top part of the screen. Upon arriving at my premises I was told that the "Call Out Fee" was R700-00 and had to be paid before they do anything. I asked them why I was not informed about this amount since this is what Samsung told me when I called. I paid it with great reluctance, as I needed my TV fixed. After they checked the TV I was informed that the top led backlights were "busy going" and the bottom lights are in a similar stage. At this point I asked the Service Agent as to what the approximate costs would be to REPLACE ALL THE LED BACKLIGHTS (not just the top part, but ALL OF THEM). He responded by saying approximately R2500-00 to R2800-00. On the back of this I agreed for them to go ahead and order the replacement backlights. Two weeks later the Service Agents arrived at my home to replace the "backlights". I was then handed an Invoice for the amount of R3600-00 which had to be paid again before work could commence. I detested this amount as it was way over their verbal quote of R2500-R2800.00 and that I never even received a quote where I was informed as to what the repair costs will be. Again I paid the amount and they proceeded to dismantle the TV in order to replace the "led back lights". A couple of days later I saw a white mark on the bottom left side of the TV and reported same to Samsung. After going to and fro between Samsung and Liptronics to now resolve this "new issue", two weeks later Samsung eventually agreed to send the Service Agent out again to determine what the issue was. After the Service Agent again arrived at my home to assess the issue, I was informed that the bottom back light has "dropped" thus causing the white mark on the screen. It was at his point when asking the Service Agent, but was not all the led backlights replaced? He responded no, he only replaced the top half of the led backlights and that the bottom lights now need replacing. I again questioned the Service Agent as to why only the top part of the lights were replaced and not all of them as verbally agreed and instructed, he responded that I was informed that only the top part was replaced and if I need the white mark removed from the screen I need to have then bottom led backlights replaced at a cost. I responded that, what person in his right mind will agree to have half the lights replaced and not the whole lot. Samsung has in meantime closed the file on this matter. I'll leave this here, however beware!
