Not happy at all.

I would like to express my utter disgust of the service that I have received from ADRS consultants firstly I called in on Monday to request a settlement for my account, I spoke to a consultant who advised me that my account is being handled by management and I need to send an email to ***, I did that and received no response for the whole week. I called in again today and firstly the consultant I spoke to named Thando was very unprofessional to say the least, I was very confused I did not know whether I was calling a company or it was just someone who was answering her cellphone, firstly she just greeted with a hello no company introduction what so ever when I said hello how are you, her response was “ngikhona unjani”I had to ask if I was through to ADRS and her answer was “yebo” I told her my issue and she just said “sisi angeke uthole umanager namuhla” as it is Saturday I then asked what would I need to do then her answer was “I don't know” now what can one do in a situation like this, aren’t you supposed to be a professional company? Is this really how you treat your clients?
