<prompt> Human: I am an international student frequently flying from Singapore to the UK. A few days ago, I was trying to get on my BA account to book my next flights to get back to the UK. However I kept getting an error message. I called them up and told them about the problem. They told me that they have deactivated my account due to inactivity for 3 years. I was baffled since I have used this account frequently for the past few years. After listing a bunch of flights that I have taken, they were convinced that they have made a mistake.Here is the weird part. They told me that I should make a new account and call them back after a few days. They said that they cannot guarantee the full transfer of my Avios Points from my previous account to my new one. Should I just expect to lose all the points I have accumulated from flying 10hrs flights every few months, or should I push British Airways and ask for a few refundbonuses. tl;dr: British Airways deactivated account by mistake and lost all my Avios Points. Made me make a new account and didnt guarantee a full transfer of lost Points. I wasnt sure which subreddit to post this on. Sorry if it is irrelevant  <response>: Keep hassling them. Have you got proof of the flights youve taken? Anything from the boarding passes to credit card statements for the bookings, email or text confirmations, even social media posts where youre at the gate or at your destination?
