Tuesday Vumatel phone me telling me it telkom fault for the connection of the fiber line, but they help me to connect the line after my 1 review that i was waiting for more than a month just so they can connect the line of my fiber . they made a promise to phone me Tuesday night at 6 pm to connect our fiber but up to now i did not received any feed back . im getting charge for something i cant use, this is bridge of contract.
