Ginormous disappointment

What a disappointment. The advertising sounded wonderful with the option to either have my new mattress delivered or I can collect from the closest outlet. Payment was without a glitch and then I phoned the branch to make arrangements to collect the mattress. They "forgot" to notify me that they have none in stock and it will take 10 working days for stock to arrive. No alternatives and no other options. I expected so much more.
