When customers start a project with your company and you're the one to create the software, then after a while the communication kind gets kind of placebo'd down until there is hardly any communication and your contact only replies to / mails you every 12 weeks or so and then after almost 1 year they urge you to get their shit done asap, telling you it'd better be done yesterday but you still lack information you asked for in one of your mails.

Fun fact: the record of them not responding was 20 weeks.
