Well finally a result, and what a result, but before the good news, this is how things played out.
Now I was told over the phone that the voucher would be validated within a couple of hours, so I went into the store to inquire about the voucher. Seeing the same sales chap I saw on the visit on Friday, explaining to him what had happened on the phone this morning he set about putting in the reference number for the voucher that I had been given over the phone. Of course it still hadn't been validated yet, some two and half hours after the phone call that morning. He told me that there were two choices, I could either go home and phone them, or he could try from instore now. He also Informed me that if I wasn't happy about the amount of the voucher then I would have to speak to them with my reasons why I thought the amount needed to be amended. I was thinking that is great except I would probably have to go home to do that, so I could have the website screen in front of me with all the specs of the different sets, why couldn't they just tell me the amount over the phone in the first place, cutting out another trip to the store.
Anyway after chatting for about 20 minutes in between him serving other customers, he tries the voucher code again, and bingo it has been validated.
He says to me with a straight face, " oh dear your not going to like this, they reckon a suitable replacement is the Samsung UE60H7000". Now this wasn't one of the model numbers that I had been looking at so I had no idea what it's price was, the assistant then smiled telling me the voucher was worth.....£2,299
I was and still am to some degree stocked and shunned, I was ready to argue with them to get the price up to around the £1,500 mark and then be prepared to pay and extra £1,000 to get the LG 65LA965W 65" 4K set. But in the end the same set has cost me £230 with express delivery for tomorrow.
The icing on the cake is that the new service agreement is only £8 a month, so that is half the price of the previous £15.99 a month.
ps. not forgetting that LG offer a free 8.3" LG pad tablet with each 4k or OLED purchase.
pps. and of course the cash for goals promotion, £10 for every goal England score or £5 for every goal Brazil score, not sure which way I'll go with that one yet.
Overall I'm a very happy camper.
