No secure internet connection - VUMA

I am busy with online studies in the US and for the past two weeks my internet was constantly on and off. A call was logged on Friday morning before 05:00 and VUMA only send a technician out at 17:30. Apparently the mistake was with a tower and I was told that it was fixed. Now, once again, I have deadlines to meet and I do not have secure internet connection. This is really starting to annoy me, to say the least. Can something please be done about this, as logging a call is useless.
