Zando incompetence

I am so disappointed with Zando. I ordered reusable nappies ×2. I received only one. I sent an email to them, no answer. I then contacted their help line and after 3 consultations I thought i got help. The lady Said she is going to lodge a return for the item I didn't get so that I can get my refund because the supplier is not answering them.

Two days later I receive a call from a corrier person saying he is here to pick up a parcel. I explain to him and tell him I will not be giving him the item that I received. If I take the one parcel I received that would mean I will get only half my money because the return was logged for one item and not 2 and I paid for 2. I'm so disappointed in your service.
