Poor customer service experience

I signed up for the Openserve R399 P/m deal, everything went great, I got an SMS and booked my installation time. Then later on in the day, I get an email stating that a connection cannot be made because the previous tenant never cancelled his connection, but this is where the funny stuff started to happen. I was asked to reply to a no-reply email? Who does that? I was then instructed to contact an agent on Whatsapp because emails are apparently outdated, so I went through all the hassle of forwarding the no-reply email to the agent only to be told I am in the wrong department and had to be transferred to another agent, after waiting for 1 hour, the other agent told me to email my response to ***, so I did that, only to get another no-reply email stating my unresolved ticket has been closed! This was an absolute circus and a waste of my time, I deeply regret signing up to Webafrica.
