*****ulent advertising and poor customer service

I have been with MTN for probably 20 years or more. I previously held a contract, but because MTN cannot provide consistent service during load shedding in my area I did not renew my contract and use the prepaid option. However MTN chose to continue charging me contract fees for a few month and it took me 3 months to resolve the issue. Subsequently I have purchased online data which I never received and on logging a complaint I was told to wait 24 hours for the data, did not receive and then was told to wait 48 hours. I never received the data I purchased or a refund. Since then I have purchased a app only promotion of 6G which includes 3 GB night time and what I received was 3GB + 6G night data which is useless to me. I didn't bother to report as it is nearly impossible to find someone to speak to in person and everything takes hours and days to resolve. But today I purchase another promotional bundle: 4g and include 2G night time data. What I received was 2G + 4G night time data. MTN is actually committing ***** by advertising promotions which they don't honour. I am quite sure people don't even follow up because it is so difficult to log a complaint and get it sorted, so like me most people just don't bother. However, I can no longer throw my money in the water like this. I would like to change service providers but I am having trouble finding service providers with good signal and availability during load shedding in the area I live in. I will leave in a wink if I find an affordable alternative that works.
