When I call out, if the person picks up, the connection is dropped almost immediately. When someone calls the phone does not connect but I get the 'calling' tone.
I have been through the problem-solving process with the (Indian?) call centre (via my mobile) and although he was very thorough with his checks he could not find any fault on the line. He suggested trying a different handset which I have since done, but still the same problem.
I'm so sorry to hear you're having some issues with your landline, I can appreciate how frustrating this must be and we apologise for any inconvenience caused. I've had a look into your account and I can't see any issues on our end, but I'm going to send you a PM to get some more details so we can escalate the matter for you.
Please look out for a notification in the purple envelope located in the top right hand corner of your screen.
