Poor Service

I settled my account in October 2017. A bank recently ran a credit check on me and found an outstanding inquiry - it was Telkom/Blake and Associates. I called today to request it be removed and for a 'Paid Up' letter - despite requesting it twice in October 2017 and November 2017. I was told this process would take a minimum of 4 working days - by which time I will have lost the home loan. I then contacted Telkom and they told me that they can't give me a timeline for the issue to be resolved but that "I must let it run its course". Absolutely shocking service - holding clients hostage despite having settled accounts. Furthermore, I recieved no apologies from any of the call service personal for this MAJOR admin error. Will never be using Telkom again!
