Bad service

Worst service ever! I regret buying from them, I really do, I made an online purchase on the 3rd and because I knw they don't take long to deliver or so I thought, I called their offices on the 6th then I was told I will receive my mixer on Thursday or Friday as it's in Midrand, on that same day I received an email that it was with courier but I haven't received it today, I called them yesterday n was told that the courier was at my house and there was no one to receive it which is a lie because I work from home and there are other ppl in this house so there is always someone at home, then today I got a call from Dawn wing telling me they only received my parcel yesterday n they can't deliver today imagine! I wanted to use it today, what must I do now, whats worse is that when u send email they don't reply, so I inboxed on Facebook n was told the same nonsense that I was not available when I question there was no further response, I'm so frustrated it's not even funny
