Poor communication, No Service

On the 10th of June 2015 I called LG to report my smart TV that is not showing any picture after a year of purchase. I was informed that I needed to provide a Model number, Serial Number and Date of purchase for the TV. As I didn't have the date of purchase, I had to request an archived statement from my bank (R20 a page) to view the transaction date which I then provided to LG as requested. On Friday the 12th of June a technician from LG by the name of James came to my house to diagnose the issue and informed me that there a part he needed to get so he would come back to fix my TV the next monday the 15th June 2015. He did not show up so I thought he would show up on the Wednesday(17th) which didn't happen. I then called LG each day from the 17th of June 2015 until today the 19th June 2015. I've been told that he will definately come out today (19th June 2015). On this day I get a call from LG requesting a proof of payment for the TV. Mind you this is a week later after being stood up and having no luck and I get asked for additiional information which could have been asked initially when I first logged the call.
