@Safta Hi! I'm so sorry to hear that you haven't received a reply, that must be so frustrating. I would suggest calling and emailing again because Admissions has been very busy lately, so it might take them a while to reply. Hopefully they'll clarity whether you can get in with youe current qualifications.
In terms of Fresher's Week, it's going to take place on an online platform so you wouldn't need to be in campus for it. However, I do suggest you are on campus on the day your course begins because QMUL are planning on providing both online and face to face teaching. If you can't make it to campus, however, don't worry, as all the necessary material will be online.
All the best,
Amaya.
