Card not working

I was provided a credit card from African bank when I made a loan with them in 2012. Because I was still using it I'm still paying it to date, last year around June the credit card expired and only went to African Bank in January for a new one, only to find the card not working.<br> Went back to the branch to notify them and was only told they didn't authority access and that they will send an email to probably one of the superiors to authorise. I was late with my payment month end Jan but the ououtstanding amount was deducted 2weeks after around the 11th February. I explained my card problem to the consultant who advised me to go back to the branch to get the new card working.<br> I went back and the guy that assisted swiped the card and told me it is now working. A day after I go the atm card is still ****** me transaction cancelled error.<br> Went back again sometimes last week the same guy phoned a consultant who checked everything and realised I was up to date with my payments but why the card was still blocked she didn't know.<br> She then told me she will forward the query to her boss who'll assist urgently, till date the card is still not work. Poor service from African bank ?
