SA Post Office a definite no-no for online stores

Not happy at all with SAPO. A parcel I sent went missing during the strikes last year. I have now submitted my enquiry twice as the first one never landed up where it needed to. It seems neither did the second one as I've not heard a word from them at all. I have sent photos of what the items looked like, filled out forms and attached all the relevant details, but not a word. As an online store, I couldn't recommend SAPO
