In the end I tried speaking to Avis CS who after some looking into the issue stated that the local office for whatever reason failed to apply the BA voucher. As a result I became liable for the cost. In fairness they were apologetic and have since received the mail below. Either way still a bit poor as the car hire element was 1k GBP!


May still have a bit of a moan to BA CS but main thing is that it is getting resolved albeit with a bit of time and stress!
