Bad Wifi Service from Signa-Fi

I would like to advice people not to use this company. They have really bad service. I send in my documentation and got approved. The guy told me that I was booked for the Friday, on Thursday night I phoned him to confirm and everything was set. On Friday I waited until half past four and eventually asked him what was going on he advised me that he will have to move my appointment to the next week as he booked 2 instillations for Friday and wont be able to get to me and that was after mine was booked for friday,so I told him that if it is not done on Saturday I would get someone else to do it.He then arranged for the techs to come at 10H00 on Saturday.When the techs arrived on Saturday after struggling they told me the could not find any signal.Now keep in mind that when I phoned the Boss he advised me that there is signal in my area.When the techs could not find the signal I phoned the boss and asked him what is going on as he told me that there is signal here and now they cannot find signal. He then told me that when they check on their side they can see the signal but are not 100% sure if there will be signal. Now if that was told to me from the start I would have asked that they first send out someone to do a survey and check if there is signal at my house but I was never advised that they are not 100% sure of the signal.This is really bad service for me as I advised the Boss from the start that this is urgent due to the fact that we are working from home because of Covid-19.
