Waiting 2 weeks for a call to do a upgrade

So I don't think Tellkom values their current paying customers as I have been waiting 3 days for their sales department to phone me back to process my upgrade... I went to their Festivall Mall branch TWICE and was told \We can not process the LTE upgrade for R599 as they can only do the R699 one.... I already have a product code for the R599 deal so why can't they just process the upgrade fro me?? I can't do the R699 on their website because there is still R599 spots open in my area... Just too lazy to help the customers if you ask me. And after phoning the sales department 3 times and being on hold for 30 min each I got told to go to the branch to do my upgrade. ***?!! Ooh and after tweeting Telkom my contact details and asking for assistance 3 times still no response...<br> <br> I would really appreciate it if you could please stop passing the buck and assist me with my upgrade please Tellkom. So the standard response will be : \"sorry for the inconvenience blah blah blah\". No service delivery and urgency what so ever to assist paying customers."
