Vodacom Retentions - gives you empty contracts

On a number of occasions prior to 12 Feb – I called to cancel my contract with Vodacom and after speaking to an agent – the call cuts and no one bothers to call me back. Then on 12 Feb I got through. After 1,5hrs on the call – I concluded a contract telephonically after the agent checked that there was stock of the device… You can listen to the last 15mins or so. Or the whole call if you have the time. P30 Lite device, R150 Airtime p/m, 10GB promotional data pm for 24 months, 20GB once off. For R259pm for 24 months Ex Vat… my phone would arrive in 5-7 days… When my device never arrived, I phoned to enquire whats going on, to be told that I didn’t receive it as the P30 Lite is discontinued and there was no Stock. Here I am trying to cancel my contract, you try to retain me with a good deal, I conclude the Deal (telephonic Voice Contract), and for you to not fulfil on it? Not my problem that you didn’t manage your stock control. You made a contract with me and need to fulfil it… if the tables were turned, you would take me the legal route, if I didn’t honour the contract payments. Should I be doing the same? I emailed all the customer service email addresses and no reply after more than a week. I phoned customer service todayand thorn said the new contract was cancelled on the same dat 12 feb (nobody bothered to inform me) then got transfered to Teven at Cancellations (The most deadest sounding person ever) and he too tried dangling carrots... I said I need a new device (P30 Lite or newer) - he said, we have it... wow.. was I Upset... How can you waste so much of your customers time... really!!!
