Lewis reps need to be well informed before they are sent to us.

I've received the worst service from the debt collection at Lewis stores. I'm on maternity leave and i explained to almost 5 staff members at Lewis after persistent call and home visits. Then I was handed over to vetex solutions one of their debt collection agencies. where by I made an agreement to make a payment on the 31th Oct 2021. Even after that i had a home visit from one of their reps This is extremely depressing and I can't deal with such harrassment. As I made an arrangement. How is it that the reps don't have the right information before they come to my house. This is embarrassing. Please help
