No resolution from Nedbank

Extremely disappointed - I phoned Nedbank about 2 weeks ago to query if I will be getting the R1000 for switching my salary. I was asked If I had received a call, I told them that I got pop ups on the app and then also got an sms. I did switch my salary. The lady (Ntombi) said she will investigate and get back to me. Since then, they stopped sending the smses and pop ups on the app - which tells me its all a **** and the fact that no one is getting back to me is frustrating. I wonder if I made a bad decision in switching back to the Green Bank. Please can someone get back to me and advise the outcome/resolution.
