When they haven't got back to you in months, then yes, annoy the hell out of them with a daily ticket.
2-4 weeks is completely normal for blow up's like this, yes your funds are in there, but you accepted these potential issues when YOU put them there.
Many people wait month and more...
For example my ticket 425325 November 10, 2017
And what ticket number are they on now?
631185 was posted recently, so that's 205,000 tickets over the course of 29-lets call it 30 days.
It's just my 2 cents, if you want to keep adding to the pile, you have the ability to do so.
