Poor service

Currently so annoyed with this ISP, they installed our internet few months ago, the outside Arial was ******. Now they want us to pay R1500 to replace it. We were never informed of this upon taking the service. They want R1500 yet they never bothered to send someone to come and do site survey, what’s going to happen when it gets ****** again? Are we going to pay another R1500? You either fix this or will escalate to ICASA and cancel your service. Please get your team to contact me on +***9/+***9 or email me to ***
