Shocking Attitude

VOX is shocking! I app**** for fibre in April with free installation. I was told that if I cancel within 12 months I would be liable for the installation fee. It never bothered me as I had no desire to cancel. Now I am moving to the apartment below me and they want to charge me R2700 installation fee because I HAVE to cancel my contract and take out another one according to them. At no time was I ever told and nowhere in their T&Cs does it state that if I move premises I will have to cancel my contract. Added to that I am not even moving addresses! I am moving to the apartment below me!!!! Furthermore I told them that I am in fact moving again to a different address all together at the end of November and can completely understand them having to charge me to install at a different property. But seriously, R2700 to move to the apartment below me? I would also like to add that I then got told that this is my fault because I didn't bother to ask a consultant whether or not I would be charged if I moved! I'm leasing for goodness sake! The odds of me moving within a 12 month period are pretty high! I am incredibly disappointed in their after sales service and am now looking for another service provider!
