Vodacom signal only EDGE nothing else

Signal in nearby Lanseria region only EDGE since 24 Dec 2014. Several calls to log compliant, including a previous Hello Peter.<br> Dino from data call center called back to inform me admitting that there is a signal problem with the transmission signal from the regional tower, increase of traffic cannot be handled, and said that there is a budgetary amount allocated to build/ upgrade the tower 2015 - no commitment or date provided!, in order to strengthen the signal for standard 3G signal (up to 24 Dec 2014 received 3G)<br> I have four contracts which is useless with EDGE, cannot even open internet! I feel Vodacom are in breach of contract unable to provide me with a service I am paying for, I want to know whether Vodacom will refund me monies as I have had to use alternative service providers at extra unnecessary costs, Vodacom - no answer to my question. My question to Vodacom which has not been answered, is do I get a refund, or do I invoke my consumer rights to opt out of contract due to paying for non services. I am extremely annoyed with the casual manner in which my case is handled by such a large Corporation who I feel are bulling their customers into accepting their shortcomings
