Ridiculous spike in Data Charges

I have been shocked by the bills that I have been receiving and paying MTN over the last 3 - 4 months. My bill has doubled and even trebled some months, compared to my normal bill of the last several years. Checking my statements, it's always the data charges! The funny thing is that I actually use my phone less now than ever before and when I do use it, I try my best to use it at home because we have an uncapped Internet supply, so I use our wifi. As the staff are striking, trying to phone the call centre is absolutely useless. <br> <br> Furthermore, I am not the only person who has been experiencing this exact problem, my husband, parents and colleagues have all complained of this exact same thing.<br> <br> Please can someone look into this and sort it out? I am at the end of my wits here. I feel completely abused and it feels like my hands have been chopped off. If I do not receive a satisfactory outcome to this complaint, I will gather all the information I can and report this consumer abuse to the relevant ombudsman for investigation. Looking forward to seeing whether I actually receive a response or not.
