Poor communication

I am slowly getting frustrated due to your Whatsapp communication channel. You need to find a better way that customers can get hold of somebody at Webafrica. I am getting no response to cancellation of my contract which needs to be done by tomorrow otherwise I get billed for another month. I will not pay that fee due to your poor customer service. We are immigrating in January and no longer need our connection. Can somebody from Webafrica please sort this out.
