What the hell????

2 times I have been happy with Buffalo's service, but today I'm incredibly disappointed, I placed an order on 30th of September, on the 7th I got a notification that my parcel is being delivered. 5 minutes later I got another notification they couldn't find my address and had to return it to their warehouse....like what?....why?....I phoned and asked what the problem was...she told me my address can't be found on the Google map, I tell her now how did they deliver to my house the past 2 times...she tells me she doesn't know, yesterday I phoned again the lady tells me my parcel is on hold....for what?....at 9pm last night I got a notification that it's being dispatched from the Vaal to to Jhb..... again? What's happening? I hope I get my parcel this week.
