Supposed damaged cable

I've had the most horrible experience with Home- connect. I paid R400 on the 2nd of December and when I got home my connection wasn't up as per the message I received. I communicated with them and they sent a person in the morning who told me that a cable was damaged and needed replacing. It's the 23rd today and they are still telling about trying to get ahold of Vumatel to reinstall the cable. All I have been asking for is my R400 back because they are failing to get through to Vumatel but they are refusing to give me a refund and another agent told me that the cable has been replaced over a week ago and that it was a technical issue that needed to be sorted but when I text again they tell me that the cable needs to be reinstalled. I am totally angry and have never seen a business refusing to pay back a client for a service that they cannot render at that particular time.
