This happening in sambapos an error when choosing the delivery rate (packpage delivery) error occurs when the client chooses then it calculates the delivery charge, which occurs when the client changes the neighborhood continues charging the same amount even if you delete the client and replacing the value of the delivery fee goes wrong, tried in various ways, excluded the customer, putting a different name, changing the phone, finally all the same ways and continues charging the wrong amount, sought in action and this rule and it all correct, anyone had this problem?
