Lots of that around here with medical practices too. My husband usually has to drive to his GP's office because they never answer the phone and their portal is useless ever since they were bought out by the major hospital here. It's right here in town, so only about 1/4 mile away. That hospital is buying up lots of the smaller independent offices.
Today, husband drove about 10 miles round trip to his new ENT's office in order to change an appointment. They also never answer, and last week he'd left a message, someone called back on Monday only to have a click followed by silence on the other end when he answered the call. Yesterday he tried to call back 4 times without success, so he was mad enough to go in person today. Receptionist said that scheduling is outsourced to a third party. There are numerous and frequent complaints on social media about this particular office being hard to contact, and I knew it would be a problem. It's a shame because the original office was very responsive over the years my mother used them, but they merged with a larger practice sometime last year and this is the way the larger practice runs. Simply awful.
