I think it has to do with the individual scheduler handling the particular account.
I have applied for regular shops. My app sits in the pending box. Then the shop gets bonused. I reapply. No go. Then I receive the "desperate, please, PLEASE help me!" email. I respond directly to the scheduler. No reply. Then more desperate/need help/higher bonuses/same shop - and again email the scheduler directly. After offering to do the work for THREE weeks and not receiving it, I gotta believe it's the scheduler.
I do regular monthly work with other schedulers at KSS and have no issues.
With regards to KSS and Sat Services, I have had the owner at Sat Services e-mailing a specific scheduler (multiple times) telling the scheduler to give me a specific assignment. Three weeks later...the shop still hasn't been assigned. Again, I think it's a specific scheduler.
And the shops I am applying for are not for a client I have done many shops for. And I haven't flaked/cancelled a shop/bombed a shop. And I meet the client' shopper requirements.
Don't know what I ever did to cross that scheduler, or if that scheduler has me mixed up with someone else, but it's a no go getting work from that scheduler unless the original client pushes and pushes the issue.
Or that scheduler is really hoping a certain someone else will apply for the shops they are scheduling.
Whatever it is, I just delete the emails from that scheduler.
Don't take it personally. It's most likely the scheduler having issues. And the scheduler is going through a ton of stress finding that "right" shopper instead of giving you the chance to help out.
