Best UX and customer service out of the distributors?

Hey Reddit, I am about to release a fairly large batch of songs to DSP's. I recently subscribed to oneRPM's Offstep at the Intermediate level. But so far I am having a number of issues with it. Their filters keep rejecting my artist names, they can't find my existing DSP profiles to automatically link the releases to the correct profiles, all disputes go through a ticket system which on average takes a day or two for them to reply to, and my label name is incorrect on one of my artist profiles.

If this is just how it is, I can deal with it and keep pushing. But it is going to slow me down a lot. I would hate to submit 200 tracks with them, fight uphill the whole way, and eventually have to transfer them to a competing distributor.

Do you all know a distributor with less restrictions on things like artist names, faster customer service, and a better dashboard?

All suggestions and guidance are very appreciated.
