Afrihost so unhelpful and give clients a run around

I have been trying to migrate my line from Cool Ideas to Afrihost since the 1st of July. All Afrihost does is say the line is not released by Cool Ideas, I have sent reference numbers and proof from Cool Ideas to Afrihost with no success. I have asked Afrihost to contact someone at Vumatel development to look into this matter as advised by Cool Ideas, still no success. Afrihost and Vumatel can someone resolve or is it best to take my business elsewhere??
