Consolidated Auto - Shocking Service

Took our Ford Fiesta in for the second service with only 21000kms on it. Told them the aircon was blowing warm air and we have hardly used the aircon. Got car back in the afternoon, we were told the pollin filter was extremely dirty which i immediately knew was a lie as hardly using the aircon over the 2 years it could not get dirty. I asked them when they change it as std and were told every 2 services and then I knew they were using that as an excuse. I took the car and quickly realized the aircon was exactly the same. i took it straight back and left it there. i got zero feedback and called in a few days later only to be told the workshop manager says it takes another 5 days to attend to the aircon? I called again today and still no joy getting our car back. It cannot take 2 weeks to attend to a aircon they somehow on the service day said there was no fault other than the pollin filter, you can install a new aircon in one day. They feel nothing for customer service and are happy to leave you without transport for 2 weeks. They however quickly send you mails to complete surveys in order to see unhappy clients so as not to allow Ford to call you for CSI. If you but any car less than a Mustang or equivalent you are just a number by them but what they don't realize is they drive company cars which cost them nothing and the public paid good money for their cars.
