Am i the only person who has experiences the worst service possibly known to man from Alfardan Land Rover?

I have recently purchased a Land Rover from Alfardan (so called Premier) motors and had the unfortunate experience of attempting to get an issue fixed through warranty. Firstly it took the service dept 3 days to tell me what the issue was (the AC unit wasn't working correctly which i could have told them myself)they then informed me that the part would take up to 6 weeks to arrive in Doha, in which they expected me to drive my vehicle without any functioning AC. I also had a small oil leak which i asked to be fixed, when i turned up to pick the vehicle, they informed me that this was not under warranty and i would have to pay. When i challenged them to show me a list of what was covered under warranty they could not do so, and they accepted that i did not have to pay. It is my understanding that they are simply trying it on with customers who are not willing to challenge this and i would encourage people to do so. Getting back to the debacle, i stated to Alfardam that seeing as the vehicle is under warranty that i should have a replacement vehicle as it is unsafe to expect a customer to drive around in the Doha temperatures without any AC and that Land Rover should be responsible for providing a replacement. I was told that no vehicles are avaialable and that they would contact me as soon as one became avaialable. Two weeks passed and i was contacted saying that a vehicle was available and could i bring my car in next week. When i got in, i was informed that i must pay a 1500 QR deposit, which would be refunded as soon as i returned the temporary car. Well it is over a month now and the funds still have not been refunded, after several calls on a daily / weekly basis the afetrsales manager has been in touch, and yet again no refund.
