Unknown calls claiming to be absa

<p>Receiving unknown calls from Absa as not able to give information as their number appears unknown and alerted as spam on the mobile application. Kindly note ave a credit limit set on my virgin money card if this is inconjunction with Absa. Have called and checked and was told there is no problem as their system errors unable to set the fixed limit. As they have a Direct debit set for the full outstanding monthly balance due. Hence one will not consume over the limit unless you have not set a limit.One cannot understand how they have deceived with by setting a fixed limit yet they claim one has gone beyond the limit. Not sure what the purpose of a limit is if it is fixed it's not possible to go over the limit. Have been alerted not to give any information where the number is privatised.</p>
