Hello, I have ordered from you before and I have 2 sets of sliding doors that have this white plastic piece which has a "lip" at the bottom that insert into the floor track so doors can glide open/close. This "lip" on the white plastic broke (when pressure was applied to the door) and now the door flops front to back when opening. Only parts holding the door in place are the top parts.
Can you help? Thank you in advance.
Respectfully,
Mary
