I placed an order for a new service for my house on the Nov. 17th 2020. I was GUARANTEED installation in 5 business days, for the 24th.
Since I haven't heard from them, I called to verify if I need to be there physically or not and I was told that the delivery date is now the 30th.
I talked with an agents that said I received a text message AND an email on the 18th but i received neither. When I called back to talk to a second agent he told me that the confirmation was sent on the 23rd, not the 18th..... but once again, I received nothing. (not in junk either).
Not possible to talk with a supervisor, they will try to call back in 24 to 48 hours... I'm working from home and right now I will be loosing money for 5 days because of the incompetence of this company.
Avoid at all cost, unless you don't mind being lied to, have promises changed without warning, etc.
They are cheaper, but since you get nothing for it, it's not worth it!
