Bad service CMH Haval Silver lakes

What a terrible service from Haval CMH,We went there and inquire about the head light bulb for our Haval H2 if they can help us put it in because the current one is damaged and they said to us they will be able to help us for free we can buy the light is R241.00 and after buying the bulb they said to us they won't be able to help us because they are too busy with other cars and we must pay R750.00 for labour and they never disclosed that from the beginning.I told them that I want to return the bulb because the money is too much I will take it to Haval Springs where we bought the car because they always give a best service and because our is still under warranty they will put it for us for free,the lady who was assisting us told us that they are not part of Haval group they won't be able help us for free.Their customer service sucks and I won't recommend my friends and families to go to any CMH Haval.
