Line suspended for No Reason

Line suspended for absolutely no reason, all payments always on time as it is a contract with a debit order. <br> Cannot get through to the call centre. Went in store, they're unabe to assist either as it might be a technical on the network. Told that the only way is to call the call centre, may take about an hour or 2 to get anyone to answer. While holding, line always gets disconnected after between 8 - 15 minutes, every time!<br> <br> Been trying all afternoon to get my line connected, and still no luck. <br>
