Shocking international service

Hello everyone, I am shocked by how poorly my service has been with Capitec Bank. I have been working in the UK for the past few months and need to get a replacement credit card. You think this process would be easy right? But no. (1) First and foremost the 24/7 international number which is on the back of my card does not work. No one answers after the welcome message!!! I spent about £100 listening to a ringing phone. (2) I've tried to email Capitec about 15 times. Got so far as to choose which option of branch i would like my family to pick up the new card. But still, that's where the contact ended. (3) If I get told to use the WhatsApp line ONE more time from the customer care number. I am going to lose it! I would advise all international companies, personal investors, and normal people overseas to stay clear of Capitec Bank. Because at this point they can't prove that my money is safe with them.
