Pathetic call center agent who refused to listen

I enquired about fiber at Webafrica, only to find that they were very expensive compared to other providers. I abandoned my enquiry and went with another service provider. I received a call thereafter from an agent and I explained the reasons for my decision. Now I get a call from an agent who is hard of hearing or who does not understand english. After I told him 5 times, let me talk, you LISTEN, I had to drop the call on him. Webafrica, if your call center agents don't understand english, or they refuse to listen to me, then this is the standard of service I am to expect? After this type of interaction with your call center, why would I want to make use of your services at all? I am the customer, surely I should have a say.

Pathetic to say the least!
