Still waiting for my goods to be delivered

I made an online purchase for a laptop last week Tuesday the 8th of November 2015. Got an sms notifying me that the laptop will be delivered on the 14th of December. On Thursday the 10th I got an sms to say the goods was send to the courier company for delivery. At 8h00 I phoned the call centre and asked if it can be delivered on the 14th as I was travelling and out of the office. The guy said no problem he'll arrange. Yesterday morning, the 14th I received 2 sms's to say my laptop will be delivered.... Well at 16h30 I had to phone them again to ask what time they are going to deliver. The agent at Digital Planet Call Centre said he'll contact the Courier Company and get back to me. Needless to say I didn't get any call back. Today I already phoned them 3 times to find out what's going on but every agent is just telling me they are waiting for the courier company to get back to them and they'll contact me. I'm still waiting.....<br> This is not the service I'm used to from FNB and will think twice before making an online purchase with them again. Please contact me with an ETA on delivery of my purchase!
