Poor follow-up from Afrihost regarding fibre line latency on Openserve line

I've submitted my problem to their fibre department regarding poor latency on my Openserve line. Openserve came out within a week, did nothing at all, and said they will contact me again, which they didn't. Afrihost is the intermediary between myself and Openserve. I had to phone in to escalate this 3-week old problem and I had to phone in daily to get a progress update. Most of the times I did not get one.

I've been dealing with the head of their fibre department. I've been asked to submit traceroute after traceroute. Though the staff were friendly, there has been no follow-up from Openserve, and it is Afrihost's job to make sure that happens.

The problem is with my line's latency. I have clear logs depicting poor latency at times. It has been taking too long now for Afrihost to pull up their socks and provide true after-care service regarding this issue.
