Telephone Abuse By Home Choice

On 17/11/2021 I received an sms from Home Choice confirming the change of contact numbers and on the sms I was called Mr Mabhena. I called them immediately to make them aware of their mistake, to which they resonded by saying they were not going to change the number unless the account holder calls them himself. i did not know where to find the Mabhena and plead with the agent to spare me those smses since I had nothing to do with Home Choice, she promised to address the matter and come back to me before close of business the same day. Days went by and no contact was made by HC. to my surprise on the 25/11/2021 I got an sms notifying me about the outstanding balance on my account, I again called and notified them about the persistent contacts I kept receiving from them which were irritating, and I was given a reference number and was assured the matter was going to be resolved. Today 06/11/2021 in the morning. i received again an sms from Home Choice about the same outstanding amount on my account and again I called them, and they promised to resolve the issue. i fail to understand why is it difficult to remove my number from their system and I keep using my airtime to call them, so far I have spent 28m11s on call time using my airtime but still no assistance
