Phone purchase nightmare

I ordered (order number ***) a phone on the 15 May, a package arrived on 24 May but it was a power bank & not the phone hence I had to return it. On the 30 May I received the phone, I did not have capacity to set up the phone until the 9 June. I transferred my data from my current phone to the new phone and only used it for 30 mins or less. The next day software needed to be installed which I did and then the phone requested a password, I did not set a password. I phoned takealot and Tarryn assisted me and advised they will speak to a supplier for a way forward. On the 18 June I called in and was assisted by Sinovuyo she advised there is no feedback and she will escalate. Later I received a call and was advised I could factory reset the phone and she'll ask management to make an exception for a replacement & log a return. I requested a different colour initially with Tarryn and she advised that they would be able to oblige. When speaking with Sinovuyo she advised that management would not be able to assist with a different colour as they would need to replace like for like so I agreed to a credit. Till now a return has not been logged and I've received a generic feedback. This has been a nightmare please can management contact me so the phone can be returned and a new phone with the colour I requested be delivered.
