Welcome to the Community!
The initial $20 pre payment which is discussed during point of sale is required as the Internet and home phone Line rental bundle we are offering you today is sold as Pre-paid. Therefore, there is no excess charge on your account.
As the line we are connecting will be capable of being used as a standard home phone service, the pre-payment will act as a reserve for any calls made that are not included in your bundle selection. If you choose not to make outgoing calls, then this payment will remain intact with no further payment made towards your monthly service charges.
If you have any further questions please do not hesitate to ask.
