TELKOM CHARGES US FOR SERVICES WE DID NOT RENDER

I called Telkom yesterday to confirm that I noticed there was special service messages sent from my Telkom landline to a UK number. Mrs Smit from Telkom called this morning, not very helpful and eventually put the phone down in my ear without explaining how it could be possible to send sms's from a landline since July 2019. Telkom migrated us during July/August last year. We hardly make any calls from this line but she insisted we did send messages from this number, which is impossible. We want them to credit this and we will cancel our services immediate effect.
