By new,do you mean last few months? Could be a number of things but frost springs to mind.Ask your builder/bricklayer what has happened.

Cold weather when mortar was still setting.

Something alot of people dont know is that the cement in the mortar can also be affected by the soil that has been used to fill the flower bed in. E.g. If there is Sulfate in the soil and Ordinary Portland Cement (OPC) has been used, sulfate eats it away. In this case Sulfate Resistant Portlant Cement (SRPC) would be needed.

Sulfate reacts with tri calcium aluminate which is present in most cements. Any work where the mortar, concrete etc comes into contact with Sulfate, a SRPC should be used.

Are there sufficient outlets for water release within the flowerbed/walls?

If not this could be one of the causes because of build up of water behind and forcing the brickwork to move forward.

This is very common with retaining walls and raised beds, there should be sufficient outlets for the release of the built up of water installed into the wall, similar situation to an overflow in your sink in the house.

Bad workmanship basically because if it was done correctly by a good bricklayer/builder this would not happen buy cheap buy twice if you know what I mean

( temperature for building should be 3+ degrees ) , foundations not deep & wide enough .

Could be a few reasons without seeing the wall i would say either frost has set in the mortar or there is too much damp gatehring behind the brickwork.
