Lansinoh Breast Pump Malfunction

I've been using the Lansinoh breast pump for a month now, and all of a sudden, its suction power has gotten a lot weaker. It's not working as well as it used to, and the cable seems to have trouble connecting, which causes interruptions. Even though I have milk, it is hard to get even a single drop. I trusted Lansinoh's quality when I bought it, but now it's putting me in a very hard situation. I need it to be fixed right away and this problem to be solved. Lansinoh, please live up to your reputation and fix the device quickly. If it can't be fixed, I want it replaced with a new one. Thank you.
