When Keith came home in the evening, he got straight onto it, got through to the relevant department and, after a long wait, spoke to a nice man with an Indian accent, who told him that he couldn't take a payment from his credit card and was all for sending him to the post office. (?) However, after a further conversation, during which Keith informed him that he not only could but was definitely going to take a payment from his credit card, the deed was done and normal service promised within the next 24 hours. This conversation had taken half an hour.
Yesterday, the phone was still not working so he tried again and again was left hanging on for half an hour but this time, he was then cut off.
Today, still no phone, so I had a go. I went through all the menus, choosing every permutation of choices I could in a vain effort to get to speak to a human, but no joy. I went online to try to find a phone number to try but still with no success, so finally, I dug out the paperwork for the business connection, chose a number from that at random and dialled.
Success! This time I actually got to speak for a 'real person' and within 10 minutes, our phone was working again.
What a performance. Total time spent on the phone trying to sort it all out - one and a half hours!
