This is my experience interacting with mobile telcos as well.
Even to get some simple logs from a base station you need to either ask an Ericsson engineer or, worse, wait for the Telco employee with the relevant knowledge to find time to do it. Telco employees with such knowledge are very few compared to the amount of workload they have to do, so it is hard to get them to dedicate time to help you.
