Service - Unacceptable

Logged a call on the 6 June for slow download speed, technician came out and plugged his router in but still the same, said he was going to the exchange to check there, 20 minutes later my dial tone and Internet went off, he phoned me 10 mins after that, told me he has to log a call with d - teq, told him my dial tone was not working and he told me my phone was faulty, told him my Internet was not working either now, said he would check, that was the last time heard from him and he just left it. Phoned on 8th June, told they were still looking into it, 10 June get an sms saying system has been restored, phone 10210, told problem with system cannot log another call yet, no call loged, phone on 11 June, log another call , find out that they have crossed my line with someone else's, support promised me there would be someone there in the afternoon or morning, June 12 get sms saying adsl restored, phone again log yet another call, told that technician will come out in the afternoon, June 13, today still no one came out, phoned again, told cannot get a hold of the technician, asked to speak to the supervisor, get put on hold then phone put down, this is unacceptable,
