Shocking service from awful business

I sent my spectacles in for a repair on 4 April. I assumed that as it was a minor issue they'd be able to fix it in-store. That wasnt the case and I was given a turnaround time of 3 days to them being repaired. On the 9th of April I followed up and was informed they weren’t ready. Bayside store were unhelpful and couldn’t tell me when they’d be ready. I called customer complaints and was called back to say they’d be ready by Thursday the 12th. Heard nothing from them and called again today on Monday the 16th. The store was again unhelpful and customer service promised to find out what was happening and to call me back. Have not been called back. Sorry Mellins - 12 days later after I was promised 3 days is totally unacceptable. I still have no answer on when I can expect my spectacles. Terrible service!!!!
