Limit increase

It is with great sadness that I write about Woolworth's for the 1st time. On my app I was offered a limit increase. I filled in the application received an offer, however I mistakenly declined the offer now its not allowing me to go back and accept. I called into the call center spoke to Nelly she advised she has sent an email to the limit increase department no one called. I called back was told the same things. I called again was on hold like 7 minutes. Its really disappoint for me with the service I received.
