Bad service

So last week i spoke to Moipene Phekedi on my Wesbank account, and she advised me that i can also qualify for the 25% discount and she would call me after my debit order went through so now i called and spoke to a different agent who is telling me that they can only give me the 20% and not 25%, Wesbank is so incompetence and i am just surprised that one agent can say something completely different to what the other one is now saying, please can you guys sort this out and URGENTLY call me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
