Service failure

Where to begin. My upcoming flight to Durban has been nothing short of a **** show. Initially it was supposed to be a fun fishing trip and now, I regret ever booking with BA, the first time in years that I actually use them. I paid a special luggage fee for all my equipment, which obviously I couldn't use, because comair was grounded. Now when I change the flight, I still have to pay an excess for the date change and the for special luggage fee, that I am no longer going to need. I have tried calling BA, and tried going through Flight Center, who will get their own review, and I have got nothing but the voice prompt,my last call I was on hold for 12 min. You better believe, if someone doesn't get back to me soon, when I get to the airport this week, we are going to have misunderstanding. The airlines in south Africa have gone out backwards in general, but this is ridiculous.
