A couple of days ago I went to register an IB Plus account since I thought it would be handy to have in case I needed it in the future (due to the 90 day rule on avios transfers etc). I normally credit to BAEC.

The website application process was quite terrible and kept giving me random errors, so I retried the application a few times. Unfortunately I hadn't been checking my e-mail so didn't notice the successful registration mails coming through..

I am now the proud owner of 4 different IB Plus accounts

Any suggestions on the easiest way to close 3 of them? I couldn't see any option to do this whilst logged in or in fact any form of contact details except a phone number. Having to call to close them is a bit of a hassle given I only opened it just in case I had a need in the future.
