Utterly useless

So i change bank, and in my head i think of doing the right thing by calling dstv to have my debit order banking details changed, to my surprise, the *********** gentleman that i spoke to toild me after 20 min on hold that they cannot load bidvest via phone call and that i would need to send an email with a bank statement and a copy of my ID to them and they will do it from there, so now this morning i get a call from that department where i had sent the email and an even less competent lady tells me that "We hear you want a debit order" im like, "No i have one but i need to change the details of that debit order", in a very coy attitude she proceeds to confirm my details and there after tells me that with a bidvest account i would need to go to a branch and they do it from there. I then ask her what then happens with my debit order....and with the worst arrogance ive ever heard, this idiot says "You are not even on debit order, so why are you worried". im beyond words DSTV, i really am.
