I FEEL LIKE CHANGING SERVICE PROVIDERS!!!!

I am soo ANNOYED and FRUSTRATED with Vodacom!!! I was due to upgrade on the 1st of April, called in to Vodacom not knowing there is different departments as this is the Vodacom number, Spoke to a lady from the Bytes department. She processed my upgrade and FAILED to inform me the device is out of stock, didn't offer my any coloir choices that is available NOTHING. I was only informed the device was out of stock via sms which was the Monday, 2 days later. I then called vodacom again and they advise they cannot assist me I need to call the bytes department and cancel that upgrade and "they" vodacom online has stock of the device. Spoke to more then 5 agents and eventually someone could cancel the upgrade!!! I then reapp**** online for the upgrade and when the consultant called ro confirm the sales order he never mentioned its a OPEN CONTRACT!!! once again had to cancel the upgrade for a 2nd time!!!! Reapp**** once again for my upgrade which is the 3rd time, I got asked 5 questions which has never happened before as I have been with vodacom for more then 8 years already I got one question wrong they blocked my upgrade and now I have to go into a store to unblock it!!!! WHAT THE ACTUALLY HELL!!! 10 FREAKEN CONSULTANTS LATER AND STILL HAVE A BLOCKED UPGRADE APPLICATION!!! I HAVE 3 CONTRACTS WITH VODACOM AND HAVE NEVER BEEN THROUGH THIS BEFORE!!!! I have an EVENT on Sunday and needed the device!!!! I work till 5pm and now have to find a vodacom after work that is still open, I feel like changing service providers because how can 10 people not know what they are doing!!!!!
