Call Centre | Unprofessional

I did an application 2 days ago and Vumatel has phoned me twice to do a new installation. I informed them twice that I have an existing installation at the property and have forwarded through proof of ownership and a photo of the physical installation. After I missed a call from Vumatel, I phoned them and spoke to a consultant advising me that there are two 'tickets' logged with them. One for a configuration and one for a new installation. The consultant was very helpful and assisted me in obtaining my 'VT ...." number which is allocated to a different address. He advised me to speak to my ISP and advise them of this. Well, what a joy the consultant was when phoning Cool Ideas. Very unprofessional. Advising me that the number I have is incorrect, while I am staring at the number and then telling me that's why Cool Ideas tell 'us' not to speak to Vumatel. I'm sorry, when did you tell me this, and I'm sorry, I am trying to assist in getting my fibre sorted after you are incapable of doing so. When asking how long it will take to rectify the matter, I was advised that she would say around two days but does not want to commit as it can take longer ... Very unprofessional and borderline rude.
