Damaged luggage on COMBA36190 - BA6410 - 13/10/19 - Customer service not existent

I was travelling from CPT to JHB and I found my bag damaged on arrival at ORTIA. It seems BA/Comair is beset with these problems of baggage pilferage and damage and is not doing much to resolve customer complaints. I was advised that my bag will be repaired on arrival at CPTIA. I had to pay for baggage wrap R90 in JHB so that my bag could not be damaged further as the bag couldn't close or lock. I am beyond angry because if my bag wasn't damaged I would not have had to fork out money to have it wrapped. The loan bag received was also damaged. I had to move my luggage between the two cases in public, no privacy was afforded for me to do this. I was since informed I can collect my repaired bag at CPTIA. So now its another cost for parking in CPT to collect. Why am I being inconvenienced for something I didn't cause. I asked who I should ask for at BA counters to collect my bag and am still awaiting a response. I have also been referred from one email address to another to get this resolved. Clearly BA/Comair does not need me as a traveller on their flights.
