Axxess are not able to attend to Telkom notifications

Hi. I laid a complaint with Axxess Support on 4 February 2020 about getting SMS notifications from Telkom saying ".... you are nearing your credit limit". This is despite only using 25% of my data allocation ? I have followed up many times with them via email and Facebook Messenger. On the 12th of February I got an email stating that they have requested that the SMS notifications to be switched off. Today is the 2nd of April and I am still getting these irritating SMS'es !!! I have been patient to date but feel this pathetic service should not be allowed. Please help.
