HappyNest Refused My Refund After Charging Me For Two Bags Instead of One

Although I have been a devoted HappyNest subscriber of this business for some time, this event was sufficient to cause me to cease using it permanently. When I only submitted one, I was charged for two bags of washing. My single bag wasn't completely closed, therefore somehow justified billing me for two full bags. When I contacted to ask for a refund for the second bag, I was informed this. That just makes no sense at all. They refused to accept how irrational this was when I tried to explain my side and went back and forth with them. It is wrong to charge me for something I did not send; moreover, their lack of responsibility is far more bad. Being a long-time client meant greater treatment. I felt instead ignored and taken advantage of. This kind of dubious business behaviour breaks off deals.
