Now Do You Call This Customer Service

I Mr Barnard booked my car for it's service about two months ago. Vin: MAKDD1780FN***. The service clerk told me that they will have to order me a new battery as the one installed is damaged. This is where the problem started. 2 MONTHS LATER they phoned me and said that the battery is there I must come for them to replace it. Guess what!!! The new battery is also damaged!! Why did they phone me to come and get it replaced if they didn't even test the new battery to make sure it's right!!! And I waited for more than an hour for them to come back to me and tell me that the second battery is also damaged!!! Is this going to take another 2 Months or what!!! NOW DO YOU CALL THIS CUSTOMER SERVICE'!!!!
