Dissatisfied by your service!!!!

This company was supposed to collect my return for Zando, today at work. In the morning I received an sms with the name of the driver who was supposed to collect my return... I waited for them at my place of work and finally opted to leave my parcel with the security guard just in case they finally showed up... Suddenly I received a sms saying the parcel was not collected because I was unavailable... They had my number, they could have called me since I waited too long for them but I did not receive any call. Tried calling them but I was on hold for almost an hour.. I'm really frustrated and annoyed by all of this.. I live nearby my school, if they had called me, I was gonna come by and physically be there since they did not take te parcel from the security and yet the first return they picked up from Umlazi, my home they picked it up even though I wasn't physically there... That's very strange!!!!! My Ref no is DUR ***9. Contact number is ***.... The return is supposed to be picked up again tomorrow but I'm sure they will make another excuse and i end up being blamed for the return not being picked up and yet I was available today for the parcel to be picked up... You really need to improve your customer service.
