Vodacom fibre after sales service is shocking

This is absolutely ridiculous. It is the 9th of August today and my fibre has already been reduced by 2mbps, apparently I've exceeded the acceptable data usage policy. This was not explained to me when I signed the contract for an uncapped line. I've logged queries and tried to contact Vodacom as this has been going on for months now. Still no feedback or possible resolution. Not a happy customer!
