Whatever you do, do not keep the aids past the return period unless you are satisfied with how well you hear and understand others. You have paid a lot of money to get help with your hearing. The fact that the practice doesn’t help you resolve your issues, is unfortunate.
Sometimes a lower cost aid dispensed by a competent fitter is better than the highest tier hearing aid that is not properly programed for your hearing loss.
Additionally, if you cannot switch programs and connect to Bluetooth reliably, those features are worthless. Having to spend excessive time waiting to see your fitter is not acceptable. You have paid for some level of support. Make sure you get that support in a reasonable time frame.
I started with Oticons. I love the way they sound. Over the years I have had several different models. Each new model offered improved hearing for me. I eventually switched to Philips aids. They are much cheaper than Oticons, however I hear well with them and get good followup service. The clinic that I got my Oticons from was very good but they were somewhat pricey. I opted to go the lower cost route so that I can change to the newer models of Philips without suffering financial hardship.
We all have different needs, wants and expectations. I think you might benefit by objectively looking at your situation and reevaluating what is best for you.
I hope you find a good resolution to your hearing situation.
