Extremely dissatisfied with Vodacom's handling of my internet service application

Extremely dissatisfied with Vodacom's handling of my internet service application. Despite canceling on the SAME day of delivery due to slow speeds, I've received no helpful response and quoted over R 20 000 to cancel even though the contract states I can cancel within 14 days. Multiple follow-ups, long phone waits, and unhelpful reps later, I'm still without reliable WiFi, and it was still not canceled. Forcing me to use data.
