Still waiting for contact lenses

On 14 June I went for an eye test at Specsavers Mall@Reds and asked them to order a new set of contact lenses.<br> I was told by the optometrist that it would take 3 to 4 working days.<br> On 21 June I went to pick up the lenses and discovered that they were never ordered. I asked them to arrange with the branch owner to phone me the next day. On the 22nd the branch manager (not the owner as promised) phoned me and confirmed that the lenses were not ordered. She promised to order them immediately.<br> I phoned them today to ask whether my lenses have arrived, that they told me that only one of the 2 boxes are there.<br> This is the 3rd time Specsavers have messed up my order, and it's definitely that last time they make any money from me.<br> I want them to go fetch the lenses from the supplier and deliver them to my office by Monday morning.
