FNB Ebucks query like pulling teeth

ok, now i've had it.

Logging request with my Private banker leads to lack of communication which is now obviously leading to me changing PBanker. Then phoning ebucks myself. Man, what a mission. First, doesn't matter what time you phone there will always be a message, we are extremely busier than usual? Really?? Finally talking to a consultant then my authentication only works the 2nd time round. Then halfway thru pulling my teeth the consultant all of a sudden cant hear me? After all this, guys i give up. Do you think they will call back? No, think again, utterly disgusted being a private client paying huge monthly fees and this what i get in return. Reverse my ebucks voucher transaction as i've been asking since 2 Dec 2019 and ensure it goes off my ebucks and as i initially wanted it to at the 30% off as i am on level 4.
