Vodacom Fibre

Vodacom installed fibre at my house with no explanation of how it works nor how to do the setup and password. the unit was installed in my TV room and from the day they activated the system i have had problems with my signal. When i phoned them to complain i was advised to install a booster at R50.00 a month extra cost. on which i told them if they cannot get the system to work they must remove it. If i leave my TV room to the kitchen i have no signal. If i move down the passage about 5 meters away i dont have signal. The option from Vodacom choose was to send me a cancellation contract with an amount of more than R1800.00 that i need to pay or the debit order will keep on running till i pay said amount still without proper signal from date of intallation. their sales rep Leroy Mohammed read my communication i send him but prefer to ignore me.
