ACCESS POINT SETTINGS ISSUE

I have an MTN contract phone. I am unable to make any APN changes to the MTN APN on my phone it is set to a default set of settings. <br> <br> I also have Axxess DSL data on my phone. My APN is always set to AXXESS but for some reason the MTN APN setting constantly override the AXXESS APN even though when I go and check the settings it is set to AXXESS. <br> <br> This has cost me hundreds of rands in Airtime and Hundreds of rands in Data. All I am told everytime I call the 1555 call centre is that I have to take my phone in and have it reset to its factory settings. This has been done and has clearly not worked. Everytime the phone is reset to factory settings I run the risk of data loss. t<br> <br> The MTN access point can not be deleted or edited at all and when I try and manually activate it there is an error messgae tell me to contact the operator, but they are unable to assist me. The one agent today actually told me to delete the MTN APN which just shows me how poorly trained these call centre agents are because you can't delete the default APN.<br> <br> MTn my contract finishes this month, I have been a loyal customer for 14 years. I am done. I will not be renewing this contract or any other.
