Pathetic Service from MTN

I logged a complaint on 10 November 2020 for my data bundle of 2GB being depleted on 3 separate occasions on the same day in a matter of minutes (plus/minus 8GB lost in total). I was advised that it will be investigated and feedback provided in 24 hours. I followed up on 11 November as no one had contacted me and was advised by the consultant that it was logged under the wrong ticket and should be logged as a *****, reference number provided. I followed up on 19 November, as no one had contacted me, and was advised that the ticket was still open - still being investigated. I followed up again on 30 November and was advised that nothing has been done and was given the ***** contact number to try. I phone the ***** line and was then advised they cannot assist as this number is only used to report *****, I need to speak to MTN. ABSOLUTELY SHOCKING SERVICE MTN!! I have been a loyal customer for over 21 years!! DISGUSTING SERVICE!!
