Our ADSL line was installed Sept 2017, up until April 2018 we did not receive a statement. This after numerous attempts at calling in, chatting online to advisors, and going into stores, we were told no account can be picked up on my partners name or id number. we receive the June statement with an mount oustanding, stating payment due by the 3rd of July 2018. the payment was made on the 30/06/2018, but services were suspended on the 29/06/2018. Please advise if the account is going to be credited due to no service available.
