Migrating from Business to Residential. Explained at all points during the order that we needed to keep our phone number. We have had it since 1961! Also my husband is partially sighted and disabled so very important that we keep the number that has been both work and home forever. Closing down the business means we must have this number. On the day of migration we were off broadband for 9 hours on a weekday. We lost our phone number for 3 days with no guarantee of getting it back. Complained to Chantelle who promised the "order" for our old number would be done the following day. It was not. Next day Mohammed did not grasp the anxiety and frustration of people not doing their job, did put the "order" through and offered £10 compensation. Derisory and insulting. Very unhappy about the stress and worry of no-one being able to contact the house. Hospitals, volunteer drivers, family, anyone else could not get through for 3 days. BT then shut the complaint as they say they have ordered the number to be re-instated sometime in the next 34 hours! They are hopeless and could not care less about vulnerable customers or their inefficiency.
