Poor service delivery

I order a new Fibre line with Vuma using Afrihost. I paid for it as well. Yesterday I was contacted regarding my installation but they had the wrong address for some reason, upon correcting the person who contacted me they advised that they would have to refer for changes. I then received an email from Vuma stating that they had failed to get into contact with me, which was very strange since I had SPOKEN TO SOMEONE! Since then, I have heard nothing about my installation.
