Marc Washing Machine Cleaner Left Terrible Odor—My Washer Unusable

I bought Marc washing machine cleaner expecting it to improve my appliance, but instead, it completely ruined my washing machine! The product has left such an awful, unbearable smell that I'm afraid to wash my clothes because the odor might transfer onto them. It's been four days, and despite leaving my washing machine door open continuously to air it out, the terrible odor remains strong and persistent. How can a reputable brand like Marc sell such a harmful, poor-quality product? I'm deeply frustrated and unsure what to do next, as my machine is now practically unusable. Marc needs to address this issue immediately, provide a solution to eliminate the smell, or refund the amount I spent. Stop ignoring your customers and resolve this serious problem immediately!
