Unhelpful Account Manager and Credit Controller

I have a contract on the ANGLO arrangment which qulaifies for a 27% discount. This has not been app**** since I took the contract in August. I dealt with Lloyd Heath who now does not take my calls or respond to my SMS (very unprofessional behaviour). Calvin Madondo who was very helpful sent a request to 809 to load the discount together with the proof of delivery. I was still asked for additonal documentation which I sent through. Today - 18 Dec the discount is still not loaded!!<br> Tried to get assistance from Credit Controller - Mbali Mavuso - for options to migrate my package - seemed like I was really bothering her.<br> I also requrested itemised billing - still have not received it.<br> Also my limit has been reduced to zero - which I had not requested. Called the call centre and they advised it would be corrected - stil lnot done. Am now on the phone for 15 minutes and holding to get through to the call centre.
