No more British Airways flights

I fly at least twice a month, and have used British Airways all year, proudly getting to Silver Executive Club Status. About a month ago, I noticed the price of BA's tickets were increasing substantially, and having had a few delays, and a couple of cancellations. Decided to look at the competition. I found, and tried, Safair, and found their prices reasonable, and their service excellent. I needed to fly on the 8th November and had to be in JHB at a specific time. BA met my needs, so I booked them again. On the 7th November, I received a SMS telling me my BA flight was cancelled, and I needed to go to the airport to find alternative options. I rang Kulula, got an earlier Kulula flight. Sitting in the middle row. No apology. No meal voucher. No plan was made for me. This is shocking service, and probably the final nail in the coffin.
