Dissatisfied Vuma/ Web Africa client

i have always had my service with Vumatel and webafrica however i have moved homes and requested for my services to be moved, they did not advise me that i need to cancel my current services and re-apply however they still took my debit order for the old service i was then told that i can only be reimbursed in November , So i needed my wifi connection and reapp**** for my new home and paid the upfront fee that was requested. The technicians came out on Monday to do installation only to find out it not done correctly i have been trying this entire week to get some kind of feedback from either Vuma or Webafrica and still nothing, only to find that today a technician came out and did absolutely nothing and just said he will send someone out to see what the issue is, i have called Vuma 6 times today and was put on hold and then the call disconnected . The service i have received is disgusting keeping in mind i made an upfront payment for a service i don't have. I would like for my issue to be escalated to higher and resolved at the soonest before i take the next steps to take this issue higher.
