Worst experience with MTN and DSV as a first time user

If it were possible to give them no stars I would. Posting here because it's my last resort with the issue I have with MTN & DSV

I had placed an order and paid for an MTN router on the 4th of March. Throughout the week I got all emails & proof of my order and payment, got a lot of numbers; reference number, account number, order number to track my order on the DSV website of which I've tried entering them multiple times on the DSV website the day I was given the reference numbers and also via link I got via email from '***' on the 6th, one that mentioned there's a delivery appointment set which was 11 March. The website either gave me an error

I tried calling the DSV number after seeing the error, pressed 1 so an agent would call me back. I either waited and got no call back or I'd hold and no agent would pick up and the call center would just hang up. Come day of delivery (11 March), got an SMS that it's coming today and I personally should be there as it needs my fingerprint, ID & proof of residence. I waited for the whole day. even asked for a day off at work because I was needed, which was understood yet no one came, no delivery driver called or came. Even asked the securities at the building I reside to be on the lookout for a delivery van, no one came. Tried calling again, didn't receive a call back. I'm thinking maybe they had other deliveries so again, I understand. I go on my only hope via email, there's a "track order" option on one MTN email I received (NOT DSV) & it says "delivery failed, 11 March 6:01PM" then "order placed on hold 11 March 6:01PM)

Since then I've been waiting for a call and refreshing on the MTN website because the DSV one is giving me errors, maybe to see that the delivery has been rescheduled or something but nothing.

I wrote the email above to multiple mtn and dsv complaint emails on Saturday and got a response only from MTN's customer care yesterday from one called Jabu R, Chantelle, Thato and others im guessing they are automated, only Jabu R asked for my ID number which I gave him. Same day MTN sends me an email saying my delivery has been updated to....on.... Thank you. Thats it. No date. No time . Nothing. I send an email again thinking maybe it was an error on their system, got the same thing with different names Valerie...still no date and time and im just in the dark. If all else fails I'll have to escalate it to MTNs ICASA. Now I try to track it on MTNs website that used to actually show before, doesn't show now. It's just empty.

I go on Hellopeter and Reddit and see that it's very common for DSV & MTN to do this?? Guys DO BETTER. PLEASE FIX THIS. AND IF THE router is non existent at least refund my money ke
