Zero Customer services

I'm an customer at Woolworths Financial Services with a store card and Credit, I recently did an increase with the store card less then 2 days it was finalized, well cant say the same with the credit card department. App**** on the 20th Jan up to this day i haven't received any feedback instead i get told they will get the team to call me they don't have a direct line. so basically i cant get hold of anyone.
