Poor service and inability to provide proper glass

My spectacles arrived back today for the THIRD time after waiting more than two weeks. They installed the wrong lenses in the wrong frame IE the multi-focal lenses reading glass frame. The multi-focal lenses were, for the third time out of alignment to which they bent the frame to compensate. Now the one lens is straight and the other one is at an angle which looks stupid.<br> <br> The one lens in the reading glasses was cut 90 degree out of alignment which they had to replace.<br> <br> The mistake I seem to have made is to pay the account in full before receiving the goods
