Not meeting timelines and bad Service delivery

I ordered a new telkom ADSL line at the beginning of September with 1) confirmation from the Sales Agent ( Tz Dlomo ) that my area is fully serviced and covered 2) Line will be installed between 7 and 21 working days which now expired 3) No service from call centre with all sorts of excuses. I have been calling for the last 2 weeks to check up on order and only today be told they are still working on the application and I should just sit back and wait for them. The call centre agent Thokoza Ncwabe did not want to transfer me to a manager nor escalate my concern. I am very concerned if this is the kind of service Telkom deliver before I am onboard as a a customer, what would service be like after I joined? My partner relocated from the UK and need the internet access at our house urgently, hence the reason why I insisted the sales agent to verify availability of services etc.All I want is clear answers when the line will be installed and why the delay? A phone call from the technical engineer working on my order is the least I'd expect, let's see if Telkom lives up to the service they promise to deliver.
