Capitec does not even answer my email!

I've lodged a complaint with Capitec's Complaints Management department in April already, and it's been more than a month now since Katherine's email, in which she explains that the matter is "re-escalated for investigation" and she promises to give me feedback soonest. My email 12 days later is still unanswered, and so too my email of yesterday. My complaint is valid, but Capitec simply refuses, or cannot, give me an answer to explain why they have taken the decision that they did. This tells me they realise that they are indeed wrong, but still they maintain their silence and extremely poor service to me. They don't even have the common decency to acknowledge receipt of my email, let alone answer it. I cannot recommend this bank to anyone.
