poor quality products and poor customer services

I purchased a cellphone from Takealot on the(Invens H11 Blue - R1,150.00) 26th March 2021 and after a week of using the phone it started freezing I reset the phone and it worked fine for a while and then noticed this is a poor quality phone as it would freeze while I'm on a call I finally decided to log a return on the 14th April 2021 the guy who collected the phone has an attitude asked him if he should check the phone before leaving he walked away and said no took one picture of the back of the phone - I kept receiving surveys as if a service was delivered - on the 20th of April 2021 a delivery guy rocks up at my work delivery address without notice with a sticker declined why I have no idea I then called h/o who then informed me they can not refund me as something was wrong with the charging block omgosh from freezing to charging block - I then asked for a email address as I wanted to upload pictures and a video to show that the phone do charge and that it is working the only problem the phone had was freezing I also advised when I called the return I cant afford to be without a phone - they send me a survey again I managed to get a email address for one of the managers *** I have been emailing no response - I have called and was promised call backs from a line manager the poor quality phone is now longer working it doesn't switch on so I'm asking in less then a month what do I do? do you expect me to through my money away I'm sure you aware we in the middle of a pandemic .I would advise no one to use the services of Takealot their staff and customer services disgusting not the first incident I think I am finally done
