False online advertising and bad customer service!

I have been a valued Vodacom customer for more than 15years, so imagine what I have paid your organization in premiums per month. We have 4 contracts due an for an upgrade, I decided to use the online platform. My biggest mistake it is a month later I am sitting with only one unit from the two upgraded I did after the confirmations team called me to inform me the advertised ipad mini was on back order, and I would not receive the unit. We then decided okay lets rather upgrade to the ipad 6 which was a better deal by the retentions department at R339.00 p/m. The every next day one ipad mini arrives...really! Now 2 weeks later, no collection has been booked I sit with a unit I do not want and yesterday I spoke to a manager in the upgrades department that tells me she cant trace an ipad mini in my possession. I repeatedly asked her are you sure as I have the unit still in my possession and I cannot upgrade to what I require as I have this unit one month later. She says to me I should provide her with a tracking number as its not on my profile, I request a callback today, she calls me to say without the tracking number she will now book the return...."an overnight discovery yesterday she did not know what I was speaking about but today she does." Now told that that both units will only arrive after Christmas, as it take 1 week to collect a delivery and another week to dispatch the new units.... This was 2 of my 4 upgrades. My 3rd upgrade was logged and activated last week, yesterday I had to call into to activate the data on line as I received an sms saying my data is depleted on a 5GB monthly subscription, when I called in I was told of 3 different options my contract could be and no I don't have data on my contract. When I became irritated and threatened I have a voice recoding of the confirmed contract, immediately the 5GB data was loaded....why do you have to threaten to get service, why do you assume your clients are lying! I have been calling into the callcentre every on ave 2 /3days since November when I upgraded online, I have emailed the retentions consultant assisting me on the 15/11/2018, no feedback. I sent the same email to a manager Jennifer Smith on the 23/11/2018 no response after she promised to have to addressed and feedback provided. Your company is wasting my time with staff and management that are rude dismissive do not give you an opportunity to speak when you want to escalate it they are sarcastic and speak over you. I raise my voice at frustration, then get told they will disconnect the call, which leaves me to start all over on a return call. I cant believe this is what the service at Vodacom has descended to, utterly disgusted and other clients would have moved on but after today and been advised that a process I started a month ago will only be resolved at the end of December I am starting to wonder why do I still bother. I requested a manager after speaking to a team leader this morning, she blatantly refused, I informed her I will refer to social media her words to me was I must go ahead. I would like a resolution by COB today and I will not be inconvenienced any longer. you have not lived up to any of your online advertising, faster, efficient and 14-Day return policy.
