Lack of response

I phoned to apply for fibre to home on Friday 16 November. They immediately sent me an email with the quotation and I rep**** to that email on the same day to accept the quotation. On Monday 19 November I received an email again from them requesting further documentation which I emailed back on Tuesday 20 November. Since then; nothing...... I sent 3 emails (dated 22, 23 and 26 November) asking the consultant if they received my email, what is happening next, how long do I have to wait etc, but I have had no reply. I phoned this morning (27 November) and spoke to a very irritated consultant - because there is a 4-6 weeks waiting period and my order is in progress. I am not upset about the 4-6 weeks waiting period, I am upset about not getting any response. Three emails later and a week down the line and I had to phone to get any information. The consultant just told me to phone the manager. I am not happy.....
