DISGRUNTLED CUSTOMER

Highly disappointed, received my stock last week Friday 10/06/2022 09:35 which was short delivered. I have been trying to get hold of them since then to no avail. Whatsapp, sms's, emails, facebook messenger and calls aren't answered, they eventually called me back on Wednesday 15/06/2022 at 10:35 and said that I have not paid for my order, which I politely informed them I have and that the stock needs to be delivered and that I have a very impatient/ unhappy client that I now need to refund as they order is late. It's now Thursday 16/06/2022 and they can't/ won't do anything as it is a public holiday disgraceful, why are they even still open
