Dstv incompetence, yet again

On 1 July I asked for my access fee to be cancelled, and everything that is connected to it. At end of July there was no access fee on my account,good. At the end of August my account had 2 amounts of R105 deducted. I call contact centre last Thursday and they said they had put through the necessary to have this reversed. Today I called to follow up, they claim no evidence of my call on Thursday on the system and no evidence of my call on 1 July. What is going on , are your staff just ***********? When I ask for a sms or email confirming my request I’m told “ we don't do that” , very convenient.
