CHEV CAPTIVA BAD SERVICE

We bought a chev captiva brand new out the box. Before 15000 km the keyless entry stopped working. We took it for the 15000km service we asked for a new set of keyless entry which were never ordered. Before 30000 km the car left us next to the road and where only helped 2.5 hours later that night. We took the car to chev east rand and they said that there was nothing wrong with the keyless entry and it was the battery. We collected the car and discovered that the keyless entry was bypassed and the car starts without the keyless entry. Chec east rand nenver told us the system was bypassed. We took the car back to chev east rand and after 6 weeks of waiting a new set of keyless entry keys were ordered from germany. Everything went well untill we reached +-42000 km and still the car is not fixed to standards and is not starting. We are not happy with this and would like chev south africa to get in contact with this as we can get no luck with chev east rand. This is not exceptable.
