Last night I visited this blog's domain : www.multibrand.biz and I was very surprised because I was directed to the website of Go Daddy i.e the site which I have purchased my said domain via Blogger.com, saying that the domain is for sale.
After I protested via several e-mail communications with Go Daddy admin, I was told that they will immediately fix the matter.
Due to this fact, I have decided to temporarily return to my previous domain www.multibrand.blogspot.com until Go Daddy fix my domain. I hope that it would not be long.
Sorry for any inconveniences.
