Credit Card increase without my consent.

Nedbank is the pits of a bank I tell you, daylight ****mers. That's why they don't response to to these complaints on Hello Peter. My Credit Card increased without my permission and this was after I requested for a reduction. I am happy to name and shame because it's my credit profile that is being affected. I have been following up with my banker Promice Mhlanga (East Rand Mall branch) and she has been giving me the run around. I was told my increase was done by Hlengiwe Rawula. Nedbank, please talk to your staff, I have you names of the people to enquire with. I have emails supporting what I stating here, I'm happy to forward this evidence. To make matters worse, I don't even receive my credit card bank statement, yet I'm told I owe an extra R2000. Thanks to these call centre consultants who have given me these names.
