FALSE DIAGNOSTICS and POOR SERVICE with NO TRANSPARENCY.

I took my car in for 135000km service, i called the following day, they said they need to open the engine and take it to engineering because it has a water/coolent lick on the water bottle. A laddy by the name Keagile said they might have to buy a new engine. I went to them and told them to only do service. Now i called again today and she said to me they are about to open the engine, riggt after telling her not to. I again said they must not do that. These guys take opportunity in trying to mKe money through false dignostics.
