Account locked every time for no reason.

Been using Luno for a While, never had any problems till now, Luno keeps locking my account saying

Hi Sandra, Good day to you!

Thanks for reaching out to us. ‏‏‎‎ Your account has been locked as a security precaution. We take customer security very seriously, which is why we need to verify it is you who has used this account.

After providing all proof of Identification and taking all security changes as requested by luno the account was unlocked after like 3 weeks, i depositing and logging in they locked it again saying the same things, been struggling for a month now, customer support just keep looping and taking ages to respond, problem still not resolved. ‏‏
