Shocking Service 274CWK23/6/15

I reported my business line faulty on the 23 June 2015 and have phoned on numerous occasion to get a response. Eventually a Technician arrived about three days ago and said that there was an earth problem between the house and the phone as the outside line was working. He said he didn't have a ladder and would return the next day. Well still holding my breathe. Who ever heard of a technician without a ladder!!!!
