I was not suggesting you phone around for tyres but was saying that if it were not a MB car that is what we would do.
The offer of taxis would have come because you are a Motability customer
I thought you said you already had a flat and if necessary you would drive to the airport even if it were not fixed
I guess my message was meant to be supportive but at the same time recognising that there is not a lot else which could be done. It’s extremely unfortunate the flat happened the day before you were going to the airport, have a hospital appointment and have to do school runs.
Hope it gets fixed and you find a solution.
