Wallet payout system not working. Poor call centre facilities.

The wallet payout system is not working. I have tried calling the Getbucks call centre numerous times. I get to number 1 in the queue and lo and behold I get moved randomly to 8th in queue. This has happened each time I try contact the Getbucks call centre, go from 1st to 8th, then 1st to 7th. The service is never this bad. I try contact them through Zendesk on their website and the exact same thing happens. I end up 6th in queue only to be out to 45th in queue. If there is a technical difficulty then why not notify customers via email?

All companies experience difficulties but why avoid calls and queries and not just notify the customer?
