TV Warranty Extension Promise not Kept

Selling TVs offering a one year extension on warranty on online product registration. Registered for two new top of the range TVs 3 times online and never got the promised email confirmation of the extension of the warranty. Contacted customer service and was sent a form to fill in yet again the endless serial number that is so difficult to find and all that data mining personal information. Got a short and rude reply from another service agent who signs as "Jurgen" that only online registrations will be processed. Tried to sort out via several emails getting more and more robotic and nonsensical replies. Essentially a case of misleading advertising. Hisense simply does not extend the warranty and plays games with the patience and time of customers. Evidently a weak management issue because the products are actually good even though priced arbitrarily. The top U9A unit sells everywhere for close to 40.000 Rand but for 19.999 Rand at Makro Online. Not an honest pricing policy and not an honest warranty policy.
