Account settled but Nimble group phones me every day!!

<p>My altech netstar account was handed over to Credit workx. I recieved a phone call from a consultant on 02/06/2016 asking for payment, I asked that he send me the banking details and I would make payment the same day. The SMS received from the consultant contained no banking details so i contacted Altech myself and got the details from their credit controller Nomsa Cindi. Payment was made on the same day and proof of payment emailed. On the 8th of June I get a phone call from Nimble asking me to make payment. I explained it is already paid and sent the POP to ********** <p>On the 10th I get the same phone call, they promise me to update the system, on the 13th I get another call same thing, on the 14th I get another call... They now phone me every day for something that was paid and sent to them.</p> <p>I dont understand how a company cannot update their records and load a POP... it is so frustrating to get the same call over and over again for something that I sorted out almost 3 weeks ago... Where is the service or professionalism? Does your system not work? What ever the reason it needs to be dealt with because they are wasting their own resources and frustrating the hell out of people.</p>
