Poor Customer Service from TELKOM SA

So last week I decided to take out a Telkom 40GB day and 40GB night package and just after speaking with their service consultant they sent me an sms informing that I was pre-qualified for the offer. Now when I call today to check the status of my application they are picking up wrong orders and some irregularities in the whole thing. They informed me today after calling them that my matter is being escalated. The worst thing is that they will not inform me with regards to details about the matter I have to continuously call to check-in with the progress. My biggest fear is that I've shared banking details and my ID number with that first "consultant". And I'm calling her their consultant because I requested from their official website to be called so I don't think people outside their framework would have access to that kind of information besides their consultants. I'm so disappointed at TELKOM SA for this negligence and poor service.
