I am very disappointed with britelink and vumatel, I ordered my fiber more than 3 weeks ago and got a call that my line will be installed on Tuesday the 24th of october , Then they cancelled to today the 26th of October at 8:30am, it is now 12:00pm and I have not gotten any call or email from them. When you call the britelink landline, it just rings for 30 minutes without anyone answering.
