Bad Customer Service

My dad went for an eye test at the Specsavers Hemming ways store on April 20. We were advised that the spectacles would be ready after 14 business days. He has not received the spectacles to date , the staff at the store keeps informing us that they are not getting any feedback from their lab. I have now escalated to the Area Manager and are still waiting for response. I am truly disappointed in how this matter is being handled and my biggest concern is my dad who is being inconvenienced as he is having difficulties with his vision.
