Changed business phone-line & cut internet without warning

Cut of business phone-line, internet without warning for multiple weeks
Lack of customer regard or care. Would not recommend to anyone wanting a land line and/or internet.
Recently, I got a letter from BT about our service, and when reading I found out that my mother's name was still on the bill, something I have trying to sort out for years, clearly with no progress. However two weeks ago something must have changed as when I woke on Friday 4th August, I found out I had lost all internet. As a business owner (hotel and restaurant) this is a major problem as I lost connection to all social media advertisement, but even more worryingly, all online bookings (resulting in me having to stop taking online bookings, a majority of my bookings). Customers and residents expect internet as it is advertised, so we had to apologise saying I will try and sort it out on Monday (with BT being closed after 5pm Friday until Monday). Things went from bad to worse when my son informed me that he couldn't phone us up. When enquiring further, I discovered that our phone number no longer worked (for no explained reason). I later found out the BT had changed our number without informing me. I was no a business owner with no way of taking bookings. Without internet, there is no way I can update my website or social media to my new unwanted number, and all my business cards have the incorrect number on. I had to last the weekend without any phone or internet connection (unable to take any bookings or get in contact with us for enquiries or reservation) hoping that it would be sorted by someone at BT on Monday. On Monday, I got in contact with a woman at BT and asked her to fix the change. I spent hours on the phone and made no progress. The next day I tried to get in contact with the same woman but it just rang through, no-one picking up as though she was ignoring me. As a result, I had to start the whole process again with another member of the BT staff. Once again, I spent hours on the phone (from 10 until 12:30) and made no progress. My wife then got in contact with someone else at BT, who promised to sort it out, yet we haven't heard back from him. I then recalled someone at BT and get through to another member of staff. This gentleman seemed to get really annoyed with me and was not polite at all. He told me that he would sort out the internet and phone problem in 24 working hours. It had now been 5 days without phone or internet, and was going to be a further 2 days. Any l business owner would tell you problems like this can put immense pain and stress on a business; financially, and emotionally. I waited 24 working hours, and still, no improvement. I recalled BT and when through the hours long process again, only to get told at the end that they would not be able to correct the phone-line and internet 'for at least a few weeks'. THIS IS OUTRAGEOUS! No small business can last weeks with no bookings, no reservations, and no enquiries. With a lack of customer service, or care and no-one from BT feeling any remorse, and worst of all, no apology for changing the phone-line and removing the internet with no warning, I would not recommend BT to anyone.
