why can there not be more than 1 isp in a road

I totally & fully agree! It is super frustrating when you go on the various websites & then see a special, then enter your address but because of the area you live in, you don't qualify for the price! I am a struggling single working mother that has tons of bills to pay & unfortunately need data to work! I am with rain at the moment & they are not delivering, so i need to change. I live in Wynberg Cape town & don't get the vuma reach deals of R399 which areas next to wynberg like parkwood, grassy park & retreat gets. I have queried this so many times, no response. I have posted on twitter as well, no response. I have sent emails as well, no response. Last week i get another special with bestinernet for a 10/10 line R599. So i put down my details & an agent calls me. She then gives me a price of R699. I said but it says R599, after i put in my address. I am told the R599 is openserve fibre, but my road is vumatel. I said then i will wait for openserve & i am told openserve will not come there. I remember when vuma was busy chopping up our road & putting that box against our wall without our permission, contacting them. The lady rep**** it is laid in the road for when anybody wants to use it, the infrustructure is there. Nothing from you are forced to use it! I am sure that many people would have objected to this had they know it was a matter of a certain isp monopolising an area! Vuma is by far the most expensive from all the other people. I hope you do take them to the Competition board & many people should do the same
