Customer care line

<p>A transaction went off on my account that shouldn’t have, i called the number on the sms I received ********** 107,</p> <p>i tried to query the transaction but when entering my card number and pin into the telephone key pad it tells me this is not a valid card number, then I was put through to a consultant who said that the systems were down and that they would call me back, I didn’t receive a call so i tried to query the transaction again today and still the same issue with the card number but now it doesn’t even put me through to any one it just ends the call</p>
