Makes sense.
Please keep us posted on your experience calling in. I had to do it a few weeks ago and was unimpressed by the queuing time and lack of knowledge of the first agent I got. I hope it has improved since then because there is no alternative to calling in whenever their website screws up, which is not exactly infrequent.
I used to be able to sort issues out on Twitter via DM but they did not reply to me at all last time. I'm guessing they stopped answering queries on Twitter due to the barrage of daily refund complaints on all their Twitter threads.
