MTN R269 LTE ROUTER promotion is a ****

I literally opened this contract on 01/02/24 and MTN has the audacity to charge me EXTRA bills this month for WHAT REASON I'D LOVE TO KNOW. My invoice shows 3 amounts to be paid that makes absolutely no sense. This is a total rip-off and emailing them is USELESS because whoever manages the customercare email account probably doesnt exist because there is no response. MTN you can cancel my contract now already if that's what you billing me with. Your service is disgusting and conning. This so-called R269 promotion is a **** in my opinion.
