MTN

On 12 July at 9h44 I received a phone call from a lady from Rewardsco, but I was under the impression it was from MTN. She said that it seem that my data was not adequate (O normally buy from my banking data when in need) and they can increase the minutes and my data for an amount of R90 (ninty rand) per month. I upgraded in March and reduced my package to R299 pm and this R90 should have increased my pmt to R389 pm which was still fine, but to my great shock I was debited with R648.99 and the account is three times more than it was before. I went to MTN but because it was not on their system increased, they had to log a call and it will only get attention in 72 hours. It seems that my packages was migrated which was NOT what I was told and arranged with. I want my money REVERSED and my package restored as it was before because these people are misleading customers and they end up with a sale and the customer is suffering the consequences as I lost my job in Covid and cannot afford this. I need urgent attention to this plse
