To anyone looking to close your account, don't contact Tyme, they will request certified documents and forms to be emailed to them within 4 days. Whereas it doesn't really make any difference to closing the account. It will still have to be left unused for 12 months before it will be closed.it will be available for that period and any usage will cancel the request to close the account.
If you just leave your account unused for 12 months according to @TymeGuy it will automatically close your account.
According to the call center, once the account is closed you will not be allowed to open a new account(with things developing every month this might also change)
Edit:they will not inform you of the above, despite many emails, messages on Facebook and mybb and promises to get back to me, I wasn't informed of any of the above. I had to call them, got through after 2 weeks, then only they could put the call on hold and find out the details while I was on the line.
Some good news
access to the call centre has improved, it's actually possible to speak to someone after waiting for about 7 minutes, although email communication still gets ignored at times.
The call center agents have been advised that online and international usage will be activated within the next 30 days.
