Ineffective customer service

Incredible connections has the most useless/ineffective customer service/whatsapp line. I ordered a washing machine online to be delivered at my place of residence, I then quickly contacted their WhatsApp line to reschedule a delivery date to a date at which I’ll be available to receive the washing machine on since I work all weekdays and some weekends hence I tried to make prior arrangements to a weekend I’ll be available/off of which it was a week and plus days from the day I communicated on, on the same WhatsApp line I was told it had been escalated to the relevant department and I relaxed. The following day I receive a call to say the driver is at the place of residence? I was so disappointed because why ? I scheduled a specific delivery date isn’t it ? I proceed to let the driver know that I’m not available and I had prior arrangements, the driver goes back and I assume reports to their boss why my order wasn’t delivered. I get a call from the transport team and they ask to confirm if I told the driver that I wasn’t available and I say yes, my available date is this one and I communicated this, I am surprised you’ve come to deliver. The person on the other end then confirms my preferred delivery day, in the same week I get a call from a different driver coming to deliver yet again, on the day which I said I wouldn’t be available, I’m now furious because why didn’t you note down my scheduled date. I say the same thing to this driver and yet again I get a confirmatory call to say ohh you said you wanted your delivery on a certain day. We are sorry, we’ll schedule it for that day. Now it’s that day and when I ask the customer line they are telling me my order is schedule for a different day. I’m so tired because not only did I message on WhatsApp to schedule the delivery to my preferred day but I also called more than three times on this line trying to physically change it via the call and no one has been able to assist me. I’ve spoken to Kgaogelo Queen, Tumelo and another person who’s name I didn’t get over the phone and they still haven’t been able to assist. If you have a line for us to schedule deliveries then why deliver on the days you feel like. This is a huge product I need to be at home to receive it. I’ve now resorted to cancelling my order because it doesn’t seem like I’ll ever be assisted. What’s worse is this morning I called twice of which the first person told me my delivery was out, the second person told me hell no it’s scheduled on this day. I’m so tired
