When you say the two restaurants listed on TA are not showing on the relevant map, do you mean there is no map marking at all? or they are mapped incorrectly. There are ~200 restaurants for Estepona, so I'm not up for finding your two.
There are a couple of possible ways to handle this and don't expect to see a change for several months if at all. Mismapped locations are legendary in the listings and seem to be a low priority for TA. No wonder you had no reply.
In the listings, the map has a star. Click on this for a larger map, then click on the star again. There should be a way to report the wrong location here. I am using my iPad right now and TA has just redesigned the website with the ensuing glitches that go with, so two reasons why I can't seem to test that out for you.
Another way is to go through the Help Centre using this link. Possibly the better way:
From the first drop down, choose > Listings
From the second drop down, choose > A listing has wrong .... categorized ....
Include the URLs of the two properties and provide any further pertinent info that would help.
Don't hold your breath waiting.
