Upgrade done, no device received to date.

On the 4th of May 2020, I upgraded on one of my 4 contracts via telecom. The consultant that assisted me very friendly and effective. But he failed to inform me that the phone I chose, was not in stock. This was after I had to choose a different phone as the device desired, was completely out of stock in SA and there was no indication when they would receive a shipment. I live in Kimberley and the device is supposed to go to my sister in PTA, so he said max 3-4 business days for delivery. After a week I called Cell C and they told me they don’t have *any* stock. But, BUT that they are expecting stock within the next week. I phoned again after a week - I was informed that there is still no stock. And that it should be end of May. I called on the 1st of June, they said possibly later the week. Today is the 10th, I called again. I was put on hold for my first two calls and the phone initially was cut off. On my 3rd attempt, The lady that assisted me 1) yawned throughout the conversation and 2) told me (this is the follow-up dept.) that maybe sometime in June. We asked if my sister can go to a branch in PTA and she could get a device from them, they said no. MTN and Vodacom does this? If I do it telephonically and send a proxy letter. Back to the consultant - she said I can maar cancel the contract but the upgrade dept. is closed for 2 weeks due to quarantine. It am currently paying for a device I don’t have, this forms part of the +- R5000.00 I pay to Cell C every month, on time. I would really appreciate if Cell C can come to this party and assist a loyal customer with a solution.
