Dissatisfied and unhappy

Im very unhappy with the service and way that my problem is being handled. I had a dashcam installed and since the start everything was a mess. Firstly on the day my appointment was for installation the technician didnt arrive for his appointment and i had to phone and ask is he still coming. Only the next day he came also not on time. Then my profile gets created as a business and not an individual so evertime i phone in i can not be validated. Then my debit order doesn't go thru. I have been phoning and emailing for this mess to be sorted and still nothing has been done. On Friday 7 Feb i asked for the unit to be removed and my contact canceled with no cost to me as im not at fault. Yesterday i was on the phone once again for about 30min getting put thru from one consultant to another and stil nothing was done to resolve this matter. I was informed the the supervisor is in a meeting and he wil phone me and that has not happened. I emaild once again and also no reply. If this is the way they handel mistakes from their side how will i feel safe for them to handle any other situations. Im disgusted in the way i was treated and im definitely not interested in having the unit anymore.
