Poor Customer Service

Literally the worst customer service i have ever received. Been struggling with intermittent connection for over 4 weeks now and each time i have contacted them they have failed to provide me with a permanent fix. I fully work remotely and some of these disconnections have happened in the midst of important work presentations. One of the agent even told me to go buy LAN cables and use that. What is the purpose of paying for wireless connection if i have to use a cable to get internet? I have requested for management to contact me and still waiting since the 31st of October. I am so disappointed and would definitely not recommend them at all especially if you taking Vumatel with them!!. I have cancelled my contract with them cause this is unacceptable.
