Complaint about Service Provider

We have had problems with internet since Friday. Yesterday, while repairing the internet, Vumatel put the connection for our internet into a dead port. They have now sorted this out but have messed up our optic number. We stay In a cottage on the property. Vumatel is mixing the two optic numbers up. To sort the problem out is a nightmare. In all of this loss of the use of the internet, not once have Vumatel informed our internet service provider of the problem or offered to reduce their monthly payment!
