No connection

I have a DSL line with Axxess. I started experiencing difficulties with their connectivity on Wednesday 19 May and I called into their contact centre. I was assured that I would be assisted within 48 hours. It is now Friday 21 May and I am still without connection. When I call in I was told that a technician would be assigned to my fault but they don’t know when. In the meantime I cannot work from home as I am supposed to because of their incompetence.
