Share trading - useless department

<p>I have had a suspended share in my account yet i constantly get margin call messages and am being charged interest on such. This is impossible since the share is not being traded!</p> <p> </p> <p>I have phoned twice and emailed 3 times onyl to be told it will be resolved, yet time and time again i get the same margin calls email.</p> <p> </p> <p> </p> <p> </p> <p>So many providers, not worth the hassle sticking with Investec</p>
