AAL335.00 GBP owing for 3 months, Still waiting

I was purchasing flights to London for my partner and I and was told the final price of approx. ?1200 GBP, was then directed to purchase avios to get the flights at that price, so I made payment online ?335 GBP for the avios. When I went to the next page to finalise the booking and payment the flights were approximately ?1500 GBP. It would have been cheaper not to use the avios, this was all incorrect on the [URL Removed] website. I could not get hold of anyone in any of the call centres to emailed them to get a reimbur*****t for the avios incorrectly advertised. I received an email back several weeks later to apologies (Bhairavi Dandekar, British Airways Customer Relations, Case reference is:***8) and was told to call the executive club. Impossible to get through to bu eventually spoke to someone and was told they would make the reimbur*****t. This was at the end of February. I have since then been unable to purchase new flights and and still waiting to get my money back. I have sent emails, I spoke to the call centre again, no one has been able to help and advise when/ if the reimbur*****t will be made. Flights are no longer affordable. C. Brassell - [Email Removed]
