Fee increased n false

Dear nedbank I tried so many time to call yourl on telephone by the time I phone yourl it take 20 minutes to be hold,and it runs out,so I decided to email yourl more than 16 time,not one reply,why,i am upset that nedbank increased the monthly admin fee charges of nedbank savy and did not notify me at all and also other bank like absa phoned me and told me to switch over as they will give me the rate of R89.00 month and I get same but also get credit card admin fee free as it linked,but this is false with nedbank,i should get the credit card admin fee free,if not why can't nedbank reply back to me
