Shocking Service!

We have been waiting since December to receive a call back from Nedbank regarding a query about our bond! We have phoned Nedbank 4 to 5 times and each time we are told they will call us back because someone from the correct department needs to phone us back and they never do! This is shocking service from a bank I’ve been banking with for over a decade! We even went into a Nedbank branch and we were told we have to phone in to deal with a bond query. We need someone to contact us ASAP! Our reference number is ***8
