YANBU.
I worked in customer services for over 10 years for a very big company, our customer services were top notch, our training was intensive and in general, the organisation was regarded as the best in the industry (in terms of us vs other customer service setups/training/crm etc).
But behind the scenes, we were surprisingly outdated, 10-15 year old phones/computers, would use at least 30 different customer service applications in a day, and an average of 7 or so on one call/contact. Some of the systems were still even keyboard controlled (think press esc for... press F1 for...) The investment was very much in the customer experience.
Incidentally, other companies in the same area as us, were constantly updating billing/CRM platforms, opening very swish offices, one even built their system from the ground up, it caused no end of issues, bad customer services, and all in all a mess.
So whilst yes, life is generally a fake it til you make it, companies investing in the wrong things will surely encounter problems.
Your customers won't care about swish stationary/offices. They WILL care about shitty service and will go elsewhere.
