Bad service at Telkom contract

I had contract with Telkom and January this year got a call that am due for upgrade, I asked them to call again as I was busy and still wanted to decide on the phone I would want, I got a call 01/02/2020, I chose Y9 and gave then details of delivery and 2 weeks later I called as nothing was delivered, I was told there were no notes on their system that shows I spoke to any of their consultants, I was helped again going through the same process again 2/3 weeks I called as there was nothing delivered, also different amounts of debit orders as from February yet no cellphone received, I did reverse some of them, every time I call them I get the same thing of not having any notes on the system.
