After cancelling account my service got suspended!

I have cancelled my subscription with Telkom 8 May 2018 already. I have cancelled it for 1 June 2018, but I am still getting invoiced, after I have received messages saying my query is resolved. Today I get a message saying my service is suspended? How can it be suspended if it is supposed to be cancelled? You website is a disaster, my payment history is incomplete.

Query number: ********** 6/ ********** 7/ ********** 3/ ********** 6

This is what I paid with EFT, before that I have paid at a Pick n Pay: 31/1 - R599.02 2/3 - R599 16/4 - R599 24/5 - R621.85

I want this sorted ASAP!
