You don't say what kind of car you have. If it is a modern car with fuel injection and electronic spark ignition, (both of which have "timing"), oil level or condition will have nothing to do with timing. If it is an older car with a carburetor and an ignition distributor, oil would still have nothing to to with the timing.
However, you may have not understood completely what they were telling you. All engines have a chain or belt that coordinates the operation of valves with the movement of the pistons. They are commonly referred to as the "timing chain" or "timing belt". Some (not all) engines have a hydraulic device (A "tensioner") to keep the correct tension on the timing chain or belt. This is operated by the engine's oil pressure. If your engine oil gets too low, the oil pressure drops. This can cause the tensioner to lose pressure and allow enough slack that the timing chain or belt slips and the valve timing goes off. This results in a loss of performance and possibly damage to the engine.

Oil consumption or loss is a separate matter. If it needs topping up every four months, you have very large oil loss, which can be from two ways. The obvious one is leakage - pools and drips of oil on the ground where you park and an engine that is getting dirty underneath. The other is internal to the engine, where oil is getting into the cylinders and is being burnt. This shows up as a hazy bluish exhaust.
In either case 4-month top-ups suggest your engine is not in good condition.

If you had to top up the oil just once after having the oil changed, they may have forgotten to fill the filter and rechecked the level after starting and running the engine.

Thanks for the response. 
im not sure the correct terms, but it seemed a spark plug end broke off and went into the engine. something with 2 coils they said. 
this is only after 67k miles on the car, its such a shame. the car has easily cost more to repair than the original cost of the car. 

i think im going to cut my losses and let this car go. afraid it will cost more in the long run trying to keep this one alive.

What happened to the engine that is necessitating a replacement?

The 2010 Cooper S Convertible uses the N14 engine. The same engine is used in the following models:

2007-2010 R56 MINI Cooper S Hardtop 
2008-2010 R55 MINI Cooper S Clubman 
2009-2010 R57 MINI Cooper S Convertible

Sourcing a used engine is a good solution. Here is a visual on the 2007-2010 N14 vs 2011-2016 N18 Cooper S engines. They are NOT interchangeable:
