********** Experience with Home-Connect

I moved into a new house which ive bought a week ago and i use my internet for work . I contacted C-Fibre who i am contracted to for another 12 months and requested an address change and reroute on my fibre and was really excited when i heard that the house had previously had fibre installed. I was then informed by C-Fibre that they could not complete my order as the line was still "occupied" by Home-Connect on the vumatel service. I contacted the previous home owner and was informed that they had asked for a cancellation, which seems to have fell on deaf ears because when i contacted Home-Connect on behalf of the customer i was told it hadnt been requested so i followed through and was assured that the cancellation was confirmed and the line would be released at midnight on Tuesday night 17/09/19 i keep on Liaising with Lynthis who says the problem is with Vumatel but when i contact Vumatel i get told that there is still an active service on the same line from Home-Connect. Its been a week now and i have a back log of work piling up and yet still no resolve please can i get answers ASAP as this has gone on for way too long now and im fed up with the blame game and constant having to phone for information... im starting to incur losses at this rate please assist as i do not know where i stand nor what to do
