No internet

I signed up for a 8mbps package and they installed it 20 October. Since it's installed I was not even able to have wifi for most of these 2 days.When power is off due to loading and comes back on it gives a error msg of connected without internet. I have been trying to get assistance. I was told that I must pay R250 call out fee for someone to come and reset my router. I will rather loose the R750 that I have paid for my package than to have no service at all. The reason that I looked for a better service provider in the first place were due to slow internet but I I have no internet at all.i would not recommend them at all for a service provider
