Bad customer service

On the 29 sept at 23:54 I lost my phone and on the 30th sept at around 8am I called the call center to let them know my phone is lost and how do I do a sim swap the lady told me I just need proof of residents and got to the store when I get there they wanted my id and proof of residents so I went back the following day and I asked the to block my phone and they told me that they can't block my phone because the person you got it now put in a mtn sim card in it so I should call mtn I did call mtn and mtn said telkom must give me the mtn number so that they can't assist me when I called telkom they said they can't investigate a number just for me so my phone is still not blocked and when I received a bill of that month my phone got lost it was very high it shows that I have sent 502 SMS that cost 900 and something on Sunday that I didn't had my phone and I called them in the morning to let them know my phone is lost and the SMS 's where sent to telkom call center number telkom dont have any customer service and they are *****s.
