Poor administration

CIDB sent me messages late last year to say my membership is expiring in 2017 and I need to pay R250 before end of February 2017. Which I did pay sometime in January 2017. On the 31/01/2017 I went into their offices to submit documents for the renewal and was given some sort of acknowledgement from them that I've paid and my registration will be done in 21 working days. Months went by in May 2017 I received an email saying my membership will be suspended and sent them the proof that I made the application on the 31/01/2017 and it was reinstated. On the 31/01/2017 I received an email acknowledging my application. Now my membership is suspended, someone is not doing the job there. It's affecting my business strongly. Unless their annual membership is paid twice in a year?
