No answer to new line refusal

I was approached by a lady from Customer care by Mondo for a tablet special. I declined the offer but asked about a Vodacom data contract instead. <br> An sms came back from Vodacom to say that it was refused. I phoned Vodacom myself to find out why and was put through to 5 different departments and not one of them could tell me why!<br> I have been a Vodacom customer for many years, I have 1 contract, I have a debit order which is covered every month. They have never had to wait for a payment. One of them said that my profile shows 4 lines under my name!<br> Tried to speak to Rewards Deptartment today as was suggested by a sales consultant and waited on the line for 30 minutes with no one to help me except an automated response that all consultants were busy. Telkom's turn around time is better than Vodacoms!<br> Obviously they don't need my business!
