BRITISH AIRWAYS: VERY BAD NON-EXISTENT CUSTOMER SERVICE!!!

On 17 September I arrived back in Cape Town on flight BA 059 from Heathrow. My suitcase was not on the same flight as myself. I, together with another 7 or so passengers whose cases also had not arrived, had to fill in a form with our details. On the form it was required that we gave the code of the lock on our suitcase for "custom purposes" which I did. The next day, on 18 September, my suitcase was delivered at my home. On opening it, I discovered that it had been opened and various items ****** out of my case. They had used the code of my lock, and then fastened another blue cable tie over my lock with a number on it. I phoned BA and was told that I had to lay a charge of theft with the SAPS and to fill out a claim form on line. Which I did, and I attached invoice copies of the ****** items. On 28 September I had heard nothing back yet from BA, so I sent a reminder. I also sent a reminder on 15 October, and another one on 29 October . I got a reply that they are "on the case". I still have heard absolutely nothing from them despite all their assurances that I will hear back from them shortly and that they are taking pride in providing the highest standard of customer service!!! Instead, they are totally IGNORING me!!!
