MTN - Customer service department- No service

Shocking customer service from their customer services departments and from MTN on-line. All we're trying to do is to buy one of their data packages from the on-line store. I was told they couldn't process the request as there an "open" request that has to be closed first before they can process the new request. After speaking to 4 people over 2 days, I spoke to Langa who did the on-line request again. She promised to send email with docs to sign. Following day called her to find out where's the documents only to find out that she received an email from some department saying that a request has been finalized. She did not advise me, I was expected to smell this ? I didn't know what request they were talking about. Langa said I must again speak to customer services. Spoke to 3 Busi she was going to put me through to some department, I was cut off. Spoke to Patrick who told me to hold on while he finds out, he apparently knew which department to contact , 35MINUTES !!!!!!!! later I put down the phone after having to listen to music playing in my ear. Eventually when I called I got hold of Ephraim. He was very apologetic and asked me to send him the email sothat he can try and sort it out. When I asked the next day he said please give to 12 o'clock I will then get back to you. This has been 3 days ago. NOTHING !!!!!. SO NOW I AM SITTING WITH A FINALISED REQUEST, I DON'T KNOW FOR WHAT , I DIDN'T SIGN ANYTHING FOR THIS FINALISED REQUEST AND I AM STILL NOT ABLE TO BUY AND ONLINE DATA PACKAGE BECAUSE OF THIS FINALISED REQUEST !!!!!!! I am so sick of your bad service and your staff that are unable to help.
