Mtn is bull****

The service at the MTN Direct call centre is ridiculous, did an upgrade and trying to get authorisation from my mother because she is the account holder is a nightmare, they are unwilling to assist even though none of their agents informed us that only the main account holder is able to sign for the phone, my mom is away until next year which basically means I need to pay for the upgrade done but will not even have the new phone, they are so rude and arrogant they do not even want to try to help. Even though I have all the relevant information and a letter from my mother giving me permission to sign for the package being delivered from DSV. This is unacceptable and makes a person want to move cellphone contracts to another provider!!!
