Upgrade Nightmare once again

I have had it with vodacom, pity i cannot move as i have 4 different contract lines with them but each i have to do an upgrade the service gets worse and worse and worse. I have upgraded my contract on beginning of this month and i was told the iphone xr and the watch series 4 are on back order but i can upgrade and i will get it after a few days, and i said that i will not take up the insurance until i receive both the devices as i cant be insuring something i dont have yet. to my surprise a few days later im getting smses telling my iphonexr is insured and on this number which i did not give permission to anyone, when i call the insurance section at vodacom they tell me i must go ack to the store or fill forms to cancel the insurance on the iphonexr, how can i be expected to complete some long form to cancel something i did not take up and i called the store they said i must come to the store, i was called to collect the i phone xr last week Friday but till today i do not have the watch and im told i cannot cancel the deal as its more than 7 days, but who said people should sell things they do not have.

the service i receive each time i upgrade is pathetic and it seems like its the same cos a few weeks i go i got pathetic service while upgrading online and then i thought let me do it at the store but even worse. i want the watch i upgraded to as come month end i will be billed for something i do not own yet.
