Internet connection

I was one of the first customers that received connection in my area when Vox went live and I had no issues. I have been experiencing connectivity issues for the last two months on regular basis. Vox call centre is blaming Frogfoot, but when they ask me to reset while they change their settings on other side of the line my connection is restored every time, so why blame another entity. I moved from a ADLS service provider to fibre to have the assurance of a stable connection but Vox has proofed me wrong. Shall I start looking for another service provider AGAIN?
