Blingstallation will overbill you.

Carefull with buying Blingstallation vouchers. They will make sure you pay more than whats on the voucher. I had a booking with them and they asked to come earlier than the set time. I agreed to meet them at home in 30 minutes. Little did I know the techs were already by my gate and when I got home 30mins later the tech immediately told me he will take 1,5-2hours on the job and that my voucher only entitled me to an hour of his time. As a techie myself I didnt see how the job will take an hour. Thats changing the LNB and running an 8 meter cable to the bedroom through a single wall for 3 guys. After the work was done in just under an hour, I was told I am being charged from the time they arrived at my house. My complaints that I was expecting them 30minutes later than they arrived and that I was doing them a favour as this wasnt the agreed time fell on deaf ears. They also changed connectors without my approval on cables that were in place and charged me for that. I had my wall drilled in two places one hole wasnt used and the used hole was a mess. Sent an email complaining to their supervisor without response. Just ignored I guess.
