Terrible service - call center agents giving incorrect info

Horrible customer service - I app**** for a contract on the Cell C website in February. On the 27th of February I received a mail confirming that my account application has been approved and that I will be receiving delivery within 2-3 working days. Knowing that I supp**** my work address for delivery and was going on leave on the 1st of March I emailed to find out whether I could possibly change the delivery address, I also phoned and was told that I should not be worried as Cell C currently is out of stock of the Huawei P10 Lite and I will be advised when they receive stock (in this case don't change my delivery address then). After this conversation with the call center agent I get another mail confirming that my order will be delivered by Friday (2nd of March) with the reference of 3892 so I phoned again and was told the same story - No stock. On the 1st of March I received a phone call advising me that they are at my work place wanting to deliver the cellphone , I phoned Cell C again and I was told that as soon as I get back from holiday I should call Cell C and they will arrange delivery and that is exactly what I did on the 13th of March and I was told that my contract was never approved but an investigation will be done and I will receive a phone call - never did!. Now I would like to find out what is going on at Cell C as I am told one thing when I phone and exactly the opposite happens. Will I ever get delivery of this cellphone??? at the very least the correct information will be a great start.
