..I use multibit wallet version.5.16 and i sent 1 Bitcoin on Saturday to my localbitcoin wallet address and today is Monday and it has not been received
i assume you mean you are using multibit classic version 5.16. It's out of date and can send a type of transaction the network no longer accepts.
You can choose to upgrade to the latest version of multibit classic, but the maximum fee it can pay is often too low to get fast confirmations if the network's overloaded. The devs aren't likely to fix that problem, so you are better off switching to using the electrum wallet.
The latest version of multibit classic is available here.
