Blocked for asking to be left alone

I bought a set of 6 Nivea roll-ons from takealot and when they were delivered the delivery guy mentioned that something has spilt and he was given the package as it and told it seems lotions has spilt. On the day I received the order I tried to lodge a complaint but it said product cannot be exchanged or refunded so I just took a picture and sent the complaint via email. I was then asked what would I like to open I said I would prefer a refund, they insisted on an exchange and I said I didn’t trust the replacing items wouldn’t arrive in the same state. Then I started getting SMS’s about collecting the damaged items which I rep**** to by saying I had thrown them out and if they couldn’t refund then it’s fine but they shouldn’t not schedule a pickup. Then the driver called when he was at my gate to collect, I told him I had sent 2 emails already regarding this. A few minutes late I get an sms to reschedule the collection. This after I literally wrote please leave me alone

Later that same day a friend asked me to buy them an item on the site and I found I was unable to make purchases, so instead of letting the issue go like I suggested they decided to block my account.

This was the most terrible service ever
