Bad Service No Response - Corporate Account

On 11 March I sent an email to Girly Moshoeshoe who is supposed to be taking care of our account. And got an out-of-office response giving Papi Lidovho as an alternative contact. I then sent Papi an email and he passed the buck the to Thembi Khomane saying he has escalated the case. I then sent a mail to Thembi Khomane / Girly Moshoeshoe, Themibi forwarded my mail to LInda Lengoati who in turn sent my mail to Belinda Perlee copying Thembi and Zaan Byleveld (another person now). Linda then said my questiona cannot be answered by her department and referred me to another person Bongane Madi; who is now on leave until Tuesday. Our company needs to make an urgent decision about this matter which we have been taken from pillar to post for a simple calculation; this is unacceptable itsalmost 3 weeks...considering the business we give these guys this is absurd REALLY!!!!! :(
