Spam mails and calls

I am being spammed by about 5 calls a day as well as follow up emails from nedbanks credit card call center. I have on multiple occasions said i do not want their credit card, but in the last day i have received over 5 calls and 5 emails from different employees at nedbank.

This is spam, change your practices nedbank. No one is going to get a credit card from someone who is spamming them.
