I'm not Angry, I'm just utterly disappointed!!!

Wow, this is definitely the end of Vodacom in my life, i just cant carry on understanding their foolish service and the "i only care to talk to you because i still need you to rate my service after this call". At first they cancelled my Showmax subscription, earlier this year, which i had linked to my voda account for debiting. They **** to me and said it was a system error which cancelled it and that they couldn't rectify the matter and relink the two profiles. i should rather pay Showmax via their own payment options and not Vodacom. and yet this was a special. partnership offering that these two companies were advertising to boost sales. Just recent, on the 25th Sep, i did an upgrade and was told i should receive my parcel within 7 working days, 8 days passes by, nothing happens, no delivery, no phone call and i decided i should rather call and find out what is the hold up, i was AGAIN.....informed that the upgrade was cancelled the very same day (25th). confusion hit me and my question was "how did this happen and who did it?". *Guess what they said to me* "It was a system problem which cancelled the order due to no stock availability, so what happened to perhaps calling me to inform me of this?????. lol and so the lady who assisted me tried to reclaim their trust in me, AGAIN!!! and she reprocessed everything and i was suppose to receive my parcel today. This morning i receive an email from their courier service and to my surprise the captured delivery address is not mine. i like, what is happening for really here. I then call the courier to try and rectify vodacom's mistake and give them my correct address because the parcel has been dispatched already, and was informed to rectify this with the source, "Vodacom". I call vodacom and was informed, "i should rather go to that destination and meet with the driver because should i decide to change the address, i would then receive this parcel after 2-3 working days". at this point i am ****** loosing my mind, and its now 16h25. I'm still holding with the voda clerk while she tries to liaise with the courier company till 16h58, mind you, the courier delivery time frames, as stated on the email are between 08h00 - 17h00!!!. Its now 18H47, still no call from the courier company nor Vodacom, but when they want to sell me their products, they know my number and will call me the whole day, everyday till they get a hold of me!!!! Tell me, really, what should i do in this case? I've been so loyal to this network for so many years. I've brushed off their mistakes and let things slide time and time again, now this huge inconvenience!!!
