FRUSTRATED and FED UP! I want OUT!

On 6 July I requested a telephonic upgrade on my current contract to a SIM only data LTE @ R349/month which was effected the same day. The promise by the "champion" assisting was that the upgrade could be done on the existing SIM, I could either use my mobile router or continue using the same phone and use the "hotspot" functionality for all connection needs. Since the upgrade, I have struggled with everything! When there is connection, it is excruciatingly slow whether on the laptop, iPad or phone. I have not been able to access YouTube and Netflix keeps loading, consistently giving error messages I have never seen before. Yesterday 7July I made no less than 5 calls trying to resolve this without success, instead I was being passed around to the "next expert" throughout the day. I called this morning 8 July trying to cancel, went from call centre agent to accounts person and ended up holding for 30 minutes before giving up while I was being transferred to the data support team who were supposed to make all my nightmares disappear. Last night I ended up reconnecting the very RAIN connection I was avoiding. Yes, it is as erratic as it has always been, BUT it works! I am so FRUSTRATED and FED UP! I do not want this anymore!
