Service is really bad

I have had the worst experience not only with the app but with people (customer service) who don't give me a solution!!! I've app**** for overdraft increase ****** the phone - and had to stay on my phone for 50 minutes! 2. On my app! Still waiting. I asked if it could be finalized the same day and was told so, here I am still waiting on feedback after calling in three times today NO ONE has been in touch this whole day please note I called this morning and again later on, still waiting on the promised call (your email says that someone from Nedbank will call me within a day well that's a lie !!!!
