Incorrect data contract loaded - *********** AND USELESS SERVICE

Somehow my data contract was changed. Not sure when or why, but the contract I have and the subscription you bill me for (same price though) is not the same. I have an MTN made for Home 120Gb contract used by my elderly mother to keep in contact, but now only have night-time express and youtube data (yipeee!!). Please fix your admin!!! If not incorrectly billed, you mess up my data - one way or another you keep messing up my life....PLEASE STOP and FIX THIS NOW!!!

This is now more than a month, my data again is depleted and the contract is not yet fixed. This must be one of the most *********** companies I've had the displeasure of dealing with!!!!!! E-mail and Twitter correspondence is NOT adding any urgency.
