Breach of contract-nad no responce

<p>I have been trying to resolve a problem with Vodacom since the 5th Of March 2016 without sucess, I had a 24 month contracts that expired in February, I was told that it will run on month to month basis, but I didnt know is that they alterd the conditions, but I called them when I received an SMS that my data is about to be depleted on the 5th, The guy on the other side assured me that I still have the data bundles ,i then continued to use the data, to my suprised they billed me for the data,I have queried this since the 4th of March, send several mails, no one get back to me ,they will transfere you the whole day. I withheld the payment for May with hope that someone will call me,but all I resceived was an SMS indicating that i must make an arrangement to pay,calling them never help. Finaly today,I spoke to Zelda Rambau who promised to atleast log a call,her service was better as she never hang up.</p> <p>I want someone to come back to me and sort out this unfair treatmnent, I have paid the acoount on time for the last 27 months .</p>
