Bad service on account with DSV

I cannot even give them 1 star, There head office service is pathetic. I was holding on for 35min and was cut of twice just to speak to someone on our account to find out is a query was solved that was locked last year November month and no one came back to me. I spoke to Tlotlo in January went she phoned to find out about payment and I told her about the query and she said that she saw it and she is the one who is working on our account and wil sort it out, and I did not hear from her again.
