Horrific Service

Bought a phone online on the 28th of November at Makro and on the 29th November The Courier guy sent me a WhatsApp message to confirm that they will deliver with all the details and it leads to a tracking site. When I was tracking the delivery it stated it was sent back. On Monday 2nd December I called and I was informed that I will get my order on Tuesday the 3rd of December. I emailed them and was informed that they updated my phone number and couldn't get hold of me and I've never updated any number. So the lady changed the number and told me I will receive my order the next day. I made contact with them and they yold me that I will get my order today Thursday the 5th December at 2pm. I've calling them the whole day and they are sending me from pillar to post telling that they are escalating my query. I don't want any escalation, I want my phone more especially that it has been paid for. Now I have to waste my resources calling these people every hour trying to get my phone delivered. Makro should use another courier company because The Courier Guy is just useless.
