Poor treatment - appointment with Specsavers

My GP had referred me for an audiology test because of my failing ability to hear sensibly. I attended yesterday at 11.45 and was ushered into a waiting seat. No-one took my name, nor any details of WHY I was there. I waited for in excess of 20 minutes beyond my appointed time and was then collected by a young woman who told me that she was a trainee and that it might take longer than expected to complete the process. She was very pleasant and explained everything well.
At the conclusion of the tests she began to prepare the various components which would be needed to assemble the hearing aids I needed. This had probably taken 15 minutes to this point.

An older woman opened the door, stepped inside and immediately began to talk 'at' the young woman who'd been dealing with me. She did NOT explain herself or apologise for the interruption. Their interchange took, probably, three or four minutes, whereupon the older woman said to the younger: "You have two minutes!"
I had NO IDEA what was going on, and they continued talking to each other.
Then the older woman said to the younger: "You have ONE minute!"
I was then unceremoniously and hurriedly ushered out of the consulting room and into the main body of the shop, where a younger man was waiting directly in the doorway,
The older woman took me to a desk and said something to the effect: "We need to book you a further appointment!" I was so taken aback that I wasn't able to collect my thoughts and ask why, or complain at the way I had been treated! Usually I would have done so in no uncertain terms!
I was given an appointment a week ahead.

I now ask myself: WHY was I treated that way, when the tests were completed and the ophthalmologist (?) was about to assemble my hearing apparatus? Why was the younger man given precedence? Why, when I had waited at least 15 minutes beyond my appointed start time was I not permitted to have my consultation completed? Why, when had only taken some 15 minutes to reach that stage when my consultation was peremptorily curtailed. I have written to the Specsavers "Contact Us" section of their website, which says they will try to get back to me within 24 hours. We shall wait and see whether they live up to their claims!

In the meanwhile, let me say that I AM ONE VERY UNHAPPY CUSTOMER.

P.S. In a previous life I was a Chief Officer at three of the old Community Health Councils and the officer in Charge of the CHCs under the NHS.
