Dell / First Technology / First Shop - all ****e

I bought a Dell docking station from dell.co.za which turned out to not be strong enough to power my Dell laptop (I found within 3 days and reported it timeously to both Dell and First Technologies). First Technologies is obviously a reseller for Dell as on the invoice they are named (in their emails they reply from First Shop so I assume they are same). I reached out to both Dell and First Technology / First Shop and they both point to each other for return and refund which I requested. First Technology/Shop told me I need to contact Dell whatsapp to get their consent; Dell says I must take it up with the reseller. Weeks later I have an unused docking station and no refund. The service is pathetic; they don't care. They are all ****e I am posting this on both First Technologies and First Shop reviews because at least I see with First Shop they read and respond.
