Disappointed im Vodacom service after 15 years of loyalty to them

i have received by faf THE WORST service fr vodacom. Aftsr being a loyal customer for 15years they could not cancel a cancellation of an interim month to month wifi after they had cancelled my fibre installation. when i phoned to follow up the woman at the callcentre put the phone down in my ear. Which is a horri le thng to do to a customer.... the fibre install was cancellwd after vodacomvot there 3 months late and had issues with needing more time and bookinb wrong dates etc. this was asked to be camcelled with the interim wifi, how is the install camcelled yet the wifi remains active??????? I am very unhappy with the level of servi e received and i believe ve that a network provider such as vodacom could do better, especially for a custer of 15 years...
