Well I can hardly believe it. I emailed BT this morning using their standard contact form. This afternoon my cellphone rang but I managed to lose the call when taking the phone out of my pocket. Immediately my landline rang. It was a very friendly Digital Care Advisor called Sharath Kumar from BT. He had, he assured me, rectified the difficulty I had experienced and I would have the requested service within 24 hours. In fact it had been put on my account when I checked a couple of hours later. I have to confess considerable surprise and pleasure at their speedy response and action. It would, however, have been much better if they hadn’t caused the problem in the first place.
