Ideally all cables needs to be installed behind the TVs
As well as power point or fused spur.
If your cables are hanging down from the TV
There is few options to get them hidden
1. chase a channel in the wall and install cables then plaster / make good
2. If it's plasterboard wall all cables can be ran behind
3. Panelling to cover cables joinery is involved
Hope that helps
Thanks for sending the pics on Facebook. I suggest posting a new job asking for an electrician and making it clear that you want the socket behind the tv.
You should be able to find someone so sort this out for you.
