Perth Ontario Telus / Koodo authorized dealer is one of the rudest, most ignorant women I have ever met. Zero customer service skills, operates on the belief that she is always right, and exerts this belief angrily. Witnessed her make snide remarks to several customers including a senior lady who was having trouble understanding her phone plan. Heard her raise her voice at other customers, and then when we had a complaint about an incorrect charge on our bill she raised her voice at us (even though the charge was obviously incorrect, and was eventually reversed by a Koodo call center representative). We asked if she could not raise her voice toward us and she responded by yelling at us and completely lost her temper. She had to leave the store front and take a moment to collect herself in the back of the store. She may have been having a bad day for whatever reason, but to treat customers this way is unacceptable. Completely disappointed with her lack of professionalism.
