Question about Galaxus Mobile CH Unlimited plan

Yesterday 4G on Sunrise with my old subscription Qoqa, speedtest between 10 and 12Mbps. Today I activated my new Galaxus subscription with 5g (which I didn't have before because I had an old Sunrise Qoqa subscription) and tested the speed at my office as I did the day before..... 1.5 Mbps I don't know if you're making fun of us, or if there's a deal with Sunrise to restrict the speed on your subscriptions, but this should be sorted out quickly or at least displayed in the terms of use, because I can't even upload 2 videos on WhatsApp whereas with 4G I had no problems.
