Afrihost canceled my order in error

After waiting almost 2 months for my two 100Mbps Business fibre order Afrihost canceled my order for one of my fibre line in error. I was only aware of this today when Open Serve arived today to install the fibre they said they received only one fibre line order from Afrihost. When I contacted Afrihost Fibre team they could not explain to me why this has happened. This is very bad customer service from Afrihost to not let their client know that the order was canceled and there was a problem. I am very disappointed with the service I received. I have phone many times in the past and spend countless hours on the phone with Afrihost call centre to confirm my two fibre line orders was on track. I need to know what is the next steps and how fast can Afrihost resolve this issue.
