Still waiting for my delivery

Hi there I have had really terrible experience with Makro, I purchased a SEAGATE 2 TB Backup Plus Slim Portable Hard Drive on the 22nd of November via their website to be delivered to my work. I have waited for the delivery.

Next thing I know I get an sms telling me that my item was delivered. Well, I DON NOT HAVE IT. I emailed, but no response, I called and I get a different answer each time, that it's on its way, that they will 'find out' for me. I'm still waiting. Your phone line is ALWAYS busy, I have to sit on the phone for ages before anybody answers. The order number is: MAK471451

I've had a terrible service, please somebody sort this out. I want what I purchased. REPLY to your emails PLEASE!

Regards Emilia
