Huawei Pathetic Service - No communication

We booked our Huawei P20 Mate in at Melrose Arch for Screen to be Replaced on the 9th of November 2019. We were told it will take three days after accepting the quote. On the 11/11/2019 I had to call and ask for the quote. I then received and accepted the quote and was told 5 to 7 days. I then had to call a few times to find out what is the status. 21/11/2019 am I received call from Call Centre saying It should be done by end of day but they will call me to tell me if we can collect the following day. 23/11/2019, still no call so I called the call centre again whom then escalated the repair. This is so annoying, paying over R1200.00 for replacing a screen, being without a phone for 16 days as at today and being a technician on the road all day, How pathetic can service be SR*** Our whole family has Huawei's and it makes me think when we upgrade to definitely change to another make. This should no be a No Charge and a delivery to door.
