Bad communication

After my contract expired, I informed your sales team that I would not be renewing at the time. I currently remain on a month-to-month basis, which I do not mind. However, your marketing/sales team continues to contact me repeatedly. Most of the time I answer the calls, only for the line to be dropped immediately afterwards. I contacted your sales department again this morning to request that my details be removed from your marketing list. I was “assured” that I had been added to the do-not-call list, especially since I was unable to follow the non-existent instructions provided by your useless chatbot regarding removing myself through my Telkom profile. Yet, despite this, I received another call from your sales team shortly afterwards. Please remove my contact details from all marketing and sales call lists with immediate effect.
