Unacceptable response

I own a small business on Main Road Plumstead. On the 30 March I reported that the phone line was completely dead - no dialing tone/incoming or out going calls!<br> The call centre informed me that it would take 48 hours to rectify.<br> Three days later another follow up call was made as phone was still dead - still no response?<br> Subsequently, a number of further calls of complaint was made. To no avail!<br> It is now the 14 April (over two weeks since fault was reported) and absolutely nothing has been done.<br> I am so frustrated as the landline is the life-blood of my business!!!!<br> I am totally lost for words on how I'm feeling at the moment...to a point of giving up !!!!<br> This is unacceptable.
