Reconnection of Service

On 7 September 2017 payment was made to reconnect our service, We contacted the contact centre requested re-connection. We were advised to e-mail proof of payment and that service would be reconnected within 24 - 48 hours. Today, 5 DAYS later the service has still not been reconnected. We are trying to run a business and find this unacceptable. We should be refunded for this 5 days........
