Bad service at specsavers gateway

After amazing service at the specsavers Phoenix branch I received the most appalling service from the gateway branch. Did my eye test in the Phoenix branch and was assisted by patient and friendly staff but they had a limited range. I checked online and saw that there was a much larger variety to choose from and decided to stop at gateway and see if something caught my eye. At gateway I was greeted by Catherine who proceeded to tell me that I could only try on 5 pairs of glasses as per store policy. When I told her that cannot be true as I am going to be committing to a new pair for the next 2 years and I need to be sure as to what I want she rolled her eyes. My husband then asked her how is it possible that at the Phoenix branch we were allowed to try on numerous pairs yet she is saying something to the contrary. She then proceeded to sigh and get frustrated with us. I did tell her that I did my test in Phoenix and she said that because I didn't do my test at this branch I could only try on 5 pairs. Honestly in this though economic times no business can afford to treat customers with such disdain and arrogance. I myself work in retail and we treat customers weather they are purchasing or returning goods with the same respect and courtesy because at the end of the day the customer is the reason we have a job. Catherine on the other hand is the very example of someone who should never be in customer service. I left feeling extremely agitated, dissatisfied and disappointed. The fact that I wanted added extras that I was going to pay for in cash to the value of R2600 made me feel like maybe I should just take my business where I would be appreciated because gateway clearly doesn't need my pathetic small sale. To add insult to injury the poor consultant from the Phoenix branch called my husband to ask what happened why did we go to gateway. Apparently catherine took it upon herself to call and shout at her for sending us to gateway. This is unacceptable. I am a customer the specsavers brand is national. In my mind I should be able to purchase at any branch. My information is on the system. What is the problem. Extremely unprofessional and *********.
