Welcome to TPG Community!
We're able to pull up your account using your community details and we have determined that the billing cycle of your internet and home phone are different; hence, the invoices are being generated on different dates.
We're sorry to hear that cancellation has crossed your mind but please give us a chance to assist you on your connection issue. It is evident on your account the series of connection drop outs. Can you PM to us your preferred callback number and time and we'll organise a callback with our tech team to conduct further troubleshooting to determine if the new modem issued to you last month is causing the issue.
