No client service!

I bought a Nespresso machine. And it comes with a R500 voucher for the coffee. So upon trying to redeem it, only then I see I have to order 10 packs of pods to get the discount which is not communicated on the voucher initially. Then I tried buying the bundle of 10 packs as they have a 20% discount. This is from Sunday I am trying so I sent a message. Their agents are not helpful and just said it ended but it is still on their site and app. I sent a picture of the ad as per their request and 4 working days later there is still no resolution. I also found out after buying the machine, this machine doesn’t take any other pod but Nespresso. So my issues are the terrible service from them and false advertising. This is absurd and disgusting to say the least.
