Disappointing

We have been struggling with this company for almost 2 months now. We have paid the connection fee, have been phoning and following up constantly but to date we still do not have internet. This is very frustrating for us as we work from home! Last week we have been promised that the line would be connected over the weekend, still nothing has happened. We have phoned them twice today, but now they do not answer our phone calls. Can someone from this company that will be able to assist us and not just give excuses PLEASE contact me!
