Poor Service - No feedback

I received a credit limit increase available to me on my Woolworths Store card in May, I sent through my bank statement as requested on the 21st May 2022 and to date have not received any feedback. I have had to call in 3 times already and all I get told is the credit limit department doesn't have a direct line but will get back to me by end of business on that day and to date I haven't received any call backs either. This is long past the turnaround time and this is definitely not the type of service I've ever received from Woolworths. What is going on???
