VAT added to rate already VAT inclusive

Good day,<br> <br> In December 2014 I migrated to a MTNchoice 500 package. The contract clearly stipulates the subscription rate as R500 VAT INCLUSIVE. When I received my January 2015 account, and each and every account up till my most recent one in June, MTN would charge me the subscription rate of R500 and on top of that add VAT to the amount at the end of the bill. <br> <br> I have logged a query with 808 when they were still functional. No reply even with a reference number. Then logged a query with MTNactive where I view my monthly bill-also no reply. So 2 queries later and no responses. <br> <br> Also, I noticed that my subscription fee is a different amount each month...and then obviously you add VAT to that. Why do we go through the trouble of signing a contract when 1 party decides they will do as they please? My contract renewal is coming up in August this year, if this query is not resolved I will not bother to stay with MTN.<br> <br> Regards, <br> <br> Benise Kitshoff
