After Sales Service requires major improvement

I bought a Hisense TV (75U8N) last week on Take a Lot. I went to the Hisense website to register the product in order to qualify for an additional 1 year extended warranty. Upon completing my personal details and the model- and serail numbers, I tried to submit but did not get any confirmation that the product was registered, After a few days I went to the Hisense support page and logged my issue about the absence of a confirmation whether my tv is indeed registered. I received no response from Hisense. I then followed up with a call, speaking to Lebo. I gave her the serial number of the tv and she confirmed that I will receive an SMS as confirmation. I am still waiting for the SMS.

Secondly I asked her a link or soft copy of the full user manual of the tv, (The tv only shipped with a "Quick setup type manual"). After holding for more than 10 minutes she comes back to say that she will call me back. I have not received any callback. Later the afternoon I called again to followup. Somebody else at Support answered. I asked her where I could find the full user manual, she asked me why I needed it. I would have thought that it is something that would be on the Hisense website. She let me also wait for more than 10 minutes. I was forced to hangup as my airtime was depleted because I had to wait on the line in both calls to Hisense. Hisense, I am quite impressed with your product but your after sales service is not up to standard. I am still waiting for the confirmation of registration and the full user manual.
