T3 and T4 errors on with CM700 Modem. Customer Service says ¯\_(ツ)_/¯

Let me preface by saying "Iris" was very kind and did her very best on our phone call.

Everything I'm reading points to something upstream. I am directly connected to the outside line going into the apartment. No splitters. Our copper lines are very old, and I requested that they send someone to test them - they would not send anyone out. I've been running an average of 10mbs for the past 2 days. If anyone has any advice on how to proceed I'd appreciate it.

edit: No splitters in my home. There are obviously splitters in the distribution box for the apartment building.
