HORRID SERVICE & NO RESOLUTION

HORRID SERVICE & NO RESOLUTION I have had the most horrid experience with WebAfrica simply trying to de-activate and ALREADY EXISTING line in a new premises. All they have to do is de-activate the line because I am the new owner of the property ,they previously said that the previous owners need to contact them directly to release the line earlier,that was done and than than all of sudden they can't,I don't want to use their service, I want to connect to my new ISP but they refuse to release the line early, even though I am not using it, even the previous owners asked them to release the line early and it was paid up a month ahead,but they keep pushing the blame on Vumatel and shifting me to 6 different agents on the chat group and all of them comes with different stories, I was on the chat with them for over 4 Hours, and they let you wait and wait, only to tell you they can't cancel, after 4 hours, I even phoned them, they still can't help me, all they must do is release the line, I don't need it, it's all paid up etc, but I don't want it but they say I must wait till the end of month, I am Already without internet and tv for 2 weeks waiting on them, all their agents are not clued up and the WhatsApp chat tool is absolutely useless. Dont bother using them if you expect any service at all. They are very bad when comes to service of customers ,and keeps on putting you through to a next agent,do these people not know what they are doing??
