Pathetic Service from Sales and Chat agents

I app**** to have a new service activated on Tuesday 24th Dec. Zaiytoen in sales processed everything and told me to wait for a payment ref no. I still haven't received it. On a chat with Athabile Z for 1 hour already and now he tells me I can't get a ref no cos my tenant who moved needs to cancel her service first before I can have internet. So if she left the country I can't have internet installed. Why didn't sales tell me this before wasting 4 days of my time. Why does your chat agent waste an hour of my time before giving me answers. Damn ridiculous.
