What is going on at Vodacom

<p>1.I cancelled a modem in December at a vodacom store in Secunda.But they did not cancell it and kept on charging me the fee for it.I went to them in Feb again and was told it was not cancelled.It was therefor only cancelled 15 March after amother installment was deducted.Are they going to refund me for their mistake?</p> <p>2.I took out a contract for 2 modems with 5Gb each,it is suppose to be recharged on the first of every month,but I still havent received my data.I went to the store twice,but nobody seems able to help me.I feel like taking my contracts to mtn because this is really pathetic from vodacom.I also received a huge invoice for 2 months in a row but cant see what i was paying for.When will my account be what it is suppose to be as i was told-just over R1100.Now I get a invoice for R2000 and last month R2600.According to the lady at vodacom I dont have 5Gb on each modem but 10Gb each.How on earth can i use 20Gb in a month?I would like to see what I am paying for Vodacom because I think something is not right here!!!</p>
