Suspicious activities and worst ever service

Had one of the worst ever service from Telkom last week.

I app**** for a smartphone online and got a callback from one of your agents, took a whole 1 and 30 minutes of my time of work doing the whole process for application then gave all my banking details for the lady to tell me that everything is fine I qualify and Telkom's head offices need to do their last credit check and they will get back to me in 24hrs.

Two days later i still haven't received any feedback not even a reference number or sales order number, I called and had to spend another hour on the line waiting to get through to an agent, finally after an hour of waiting I get on the line only to be told that my application was cancelled and I cant even get a reason as to why it got cancelled as I never any authorized any cancellation. To make things worse I am now sitting with an enquiry on my credit report for something that i didnt get rejected for but was cancelled without my consent. This is really bad service coming from you guys and the enquiry I have is going to have a negative impact on my credit score, how can you cancel an order without the customers consent and not even notify the customers, just leads me to thinking that you guys are busy with some ******** or ********** activity using my name cause what happened doesn't make sense at all. People warned me not to go for you guys but I gave you the benefit of the doubt and now I got burnt,

Shocking service from such a big organisation
