Debited a ridiculous amount two months in a row!!!

<p>Hi there</p> <p> </p> <p>Vodacome has debited me over R 9000 over a 2 month period stating that I was roaming. I was overseas once month and there is NO way my account was that high. Following that it states I was roaming last month when I was month and as a result my account is more than double the regular amount.</p> <p> </p> <p>I am very angry regarding this and would like someone to get in touch with me urgently. My contract is up for renewal in July and I actually might just move providers because this is very uncalled for.</p> <p> </p> <p>Thanks</p> <p> </p> <p>Dani</p>
