So much for convenience - Disappointing Service

I contacted DSV on the first weekend of June regarding a delivery I needed made from Johannesburg to Cape Town. They responded to me on the Monday with a quote and I spent the day comparing with other courier companies. And ultimately ended up choosing to use their services. Before I made payment I notified them that the parcel would be collected from myself before I catch a flight heading to CPT for JHB. The lines of communication were quite efficient until I’d made payment. I then kept calling them to ask when I could expect collection as I had a flight to catch. I got to a point where I was ready to cancel the collection as I didn’t feel like they would make it. During my process of cancellation I was asked not to cancel and they’d ensure the package was collected ASAP. Because at this point I did not have a plan B, I accepted this request. They eventually came and collected the package. I asked for a waybill and was told it would be fill out at their offices and mailed to me as they were in a rush to get my package out. As I was also rushing to the airport and didn’t have much time to query this I let it be. Because I had paid for an express service I was expecting my package the very next morning on the 6th of May, 12pm latest. No delivery was made. After 12 I then started making the relevant calls. Sent from pillar to post. Told their systems were down etc. at this point all I have is my 6 digit UTI number, hadn’t been supp**** with a tracking number. Fast forward to Thursday afternoon on the 7th. I’ve been finally given a tracking number and have hopes of receiving this parcel. Only to find it had only been sent out on the 6th that it was supposed to arrive on as opposed to the 5th. The delivery had apparently failed as ‘there was no one at the house’. I have been basically on house arrest waiting for this delivery. Not once did I receive a single phone call stating there were delivery people at my gate. Since that single attempt to deliver on Thursday nothing has been done. With every phone call I make, my query is being escalated. It is 6 days later and still no delivery. I have even requested to collect the parcel myself from their warehouse and I get told they first need to locate it and will either email me or call me in an hour or so which never happens. As someone who chose DSV and was willing to pay their prices for their convenience I have gotten the complete opposite. The delivery I have been waiting for for a whole 6 days is for my desktop, as a freelance designer I have been crippled by this company as I have not been able to work and therefore have not been able to make money. I would never recommend this courier company to anyone after such a bad first experience. All I can do is remain hopeful that it will eventually arrive. The amount of airtime I have wasted calling, been put on hold at times for up to 10 min, with no solution on the other end is just a bit too much as well.
