Analysis of 3,096 fiber optic subscribers shows a direct correlation between latency spikes (>30ms) and churn events within 30 days. Enugu TX degradation currently places 340 subscribers in the high-risk queue. Proactive intervention (speed guarantee offer in local language) could prevent ₦25.3M monthly revenue loss.

2,341 subscribers on month-to-month contracts with no TechSupport add-on represent 33.2% of all churners despite being 23.5% of the base. Bundling tech support into month-to-month plans could reduce this segment's churn from 41.6% to an estimated 15.2%, saving ₦68M monthly.

The WAXAL dataset (2,000+ hours West African speech: Hausa, Yoruba, Twi, Pidgin) fine-tunes a Whisper ASR model that transcribes customer support calls in real time. A Hugging Face multilingual BERT classifier then extracts dissatisfaction signals — "My network dey do anyhow" (Pidgin, frustration), "Kuɗina ya tafi" (Hausa, billing complaint) — and feeds them directly into the churn risk score. Today, 847 calls triggered churn risk elevation after multilingual NLP flagged high-dissatisfaction language patterns. Without multilingual processing, these signals would be invisible to English-only models.
