Seriously reconsidering why I have a Builders' account!!!

I called just now - just to apply for a credit increase on my already existing Builders' account. I selected the credit increase option after listening to the prompts, eventually reaching an agent just to be put through to store cards, then eventually being put through to customer care, then again being put through to master cards and then being put through to another department after which the call was answered but no one was talking and then mysteriously the line went dead??? What the hell??? How difficult can it be to assist the customer calling clearly explaining from the beginning that she wants to apply for a credit increase on her existing Builders' account??? Really??? What a total waste of time, airtime and patience for 20 minutes and 35 seconds...
