Brand new installation broken after TWO days

On the 12th of February 2016 we requested that telkom comes out and does a new installation for DSL and phone line. They came out on 22nd of February 2016 and the technician said that the cabling is damaged and they will have to come back out again. On the 26th of February 2016 they came out again and completed the installation. We are using Mweb as our ISP and we had to wait for telkom to do the installation before we could get anything from Mweb. On the 29th of February 2016 we spoke to Mweb and they dispatched the modem to us. On the 1st of March 2016 we got the modem and was finally able to access the internet. Now on the 3rd of March 2016 we are down. We are informed that the problem is at the exchange and I do not see why there could be a problem as this is a new installation of which we have to wait 7-10 working days for a technician to come out and fix this problem meaning we will be down for almost two weeks after waiting two weeks for them to come and install it. I am really disappointed. Now we paying two parties for a service we are unable to use.
