Faulty Mecer Z140C New Compact Design laptop

I have got an out of box factory fault and bare in mind I asked the delivery guy to wait for me to check if everything is working but he left and said if there is a fault I have to call within 7 days of which I found out that my laptop that I bought had a faulty keyboard for example when you type 'Z' it inserts a 'Y' which this is only a single example of all the keyboard issues i am currently facing, I got this deal with a low credit score they then told me when i called the 3rd time which was on the 26th of February 2019 of which delivery was on the 22nd samde month, I called three times trying to get this laptop picked up but even today it has not been collected and there is no contact whatsoever from vodacom to show that they care about this client/customer, I am now facing an issue that i was told by them that my credit score is low and that if they collect the laptop they now have to cancel the contract and then i must start afresh, what if I am not approved?

I demand an auotmatic approval soonest this laptop is collected, now another thing is I then have to wait for more than a week for them to literaly collect the faulty laptop and my problem is I need for both home, work and studies and I am currently stuck because it is faulty and shows strange files inside it so I may be scared it might have more issues than what I have seen already.

I need this outrageous issue sorted out soonest and i need approval of getting another laptop from vodacom, i dont want to cancel my contract but need a new better working none faulty laptop. ASAP as it may. ndidikiwe shame.
