Bad experience

First I had an upgrade due in September 2017. I requested a Samsung A7. I waited 2 weeks where nobody even bothered to contact me to tell me they did not have any stock - I had to phone them to find out. I waited another week for this phone and when someone finally told me it will be delivered I lapsed into another month and got told now I have to pay the increased contract amount?! How is this even possible if I upgraded 3 weeks prior to increase amounts but due to the poor service now I have to pay more? I cancelled my whole upgrade. I got a phone call telling me that because of poor service I am rewarded 1gig of data for the next 6 months - at least something good came out of it! Then later decided to try and upgrade again. I asked for the Samsung A5 and everything went smooth until an hour later they phoned me to say "I cant get the A5 on the contract that they advertise everywhere" - I told them but you advertise it, I could not even get a clear explanation as to why I cannot get it on that contract but anyway what can I then do right... So very upset I asked them what phones do they have on that contract and then took the J7 prime. NOWWWWWWW I find out that my 1gig wasn't loaded for December and when I phoned they could not even pick it up on the system and got asked who told me that I may receive 1gig - like Im the one lying! I still have until March 2017 to receive my 1gig. A huge fight again and eventually got told they will follow up. My point is I am paying for a good service and its not cheap! I moved to Cell C because I was promised good service - so far I am very disappointed! Lets hope this gets resolved.
