Vision Express — Regarding pathetic service of contact lenses

I have placed an order for contact lenses on 26 Jan during purchase i was told that lenses are present at nearby stock and will get it delivered in one week time .However after 20 days when we visited store we were told only right eye lenses available and left eye lenses will take time .Its really illogical that someone will take one side eye lenses so we requested them to get the left lenses also .Again after one week we visited store and again same story we were told.This is really disappointing for the customer to do follow up again and again and there were no prior information from store or Any call msg from their side that delivery is delayed.Atleast we as customer need to know if delivery is getting late
