Mixed. Call handlers were helpful. First mechanic came within 30 minutes. Changed burst tyre and recharged battery and said I was good to go. I expressed my concern that before the blow out there was a noise from under the car and I was worried about continuing my journey on the motorway. He said everything was fine, the tyre was just poor quality and basically left me without further checks. I started to drive off but the noise was still there. Called helpline again. They said they could not arrange the car to be towed home until the afternoon of the next day! I needed to get home earlier so took the train which they refused to cover the cost of. The driver of the delivery truck correctly diagnosed a broken mainspring which had gauged a hole in the tyre. If I had followed the advice of the first mechanic I would have gone onto the motorway which was 5 minutes away and the second tyre would also have burst with potentially catastrophic results! The driver of the pick up lorry was extremely helpful and friendly.
