Thank you for your wisdom and experience sharing Mary. My experience mirrors yours quite a bit.
It's so important to have a provider that is willing to work with you when things aren't as expected. Everyone is different. Unfortunately, one of the similarities among people who are struggling with hearing loss is to be frustrated and displeased with the product and the provider.
Many whom I know have been very happy with hearing aids fit and provided by big box retailers like Costco. Others are not. The training of the fitter is extremely important as is that person's patience with the frustrated hearing aid buyer.
And yes, every person's hearing loss is unique. Some are far easier to fit than others. That's where the experience of the fitter comes in big. It's also where issues that go beyond basic hearing loss might be in play.
Fitting hearing aids properly is a skill, particularly when the person being fitted has a unique loss. Most progressive hearing loss is caused by noise exposure, drug interactions, or normal aging. However, it can sometimes be caused by medical issues that need treatment aside from hearing technology.
The audiology profession has had to adapt to a lot of changes. It's important for all of us to know that some of the fitters/providers have doctorate level degrees in the field, they are AuD (Doctors of Audiology), others may have a master's degree and be identified with the letters MS-CCCA or MA-CCCA for master's degree certified clinical competence in audiology.
Many who work as assistants or at the big box stores have far less education and are called 'hearing instrument specialists'. HIS requires no college degree at all, but training in the field as an apprentice.
If a person's hearing loss is not complex, basic amplification may be all that is needed. However, if it is more advanced and unique it may need many adjustments before it feels right.
Important though, is to understand that hearing aids do not 'cure' hearing loss. They do not fully correct it either. They are 'aids' to better hearing. People who adjust to using them usually find they are extremely helpful, and greatly missed when not available.
