Shocking service

Once again poor service from vodacom I'm on a 50mbps up and down line and I'm only getting 21 2mbps. I phone the vodacom fiber call centre once again, no help from them all they worried about is ref number and what date and not even intrusted in sorting the problem out. I'm going to go into vodacom tomorrow and tell them to take their *** equipment out of my house as it is a breech of service they promised to deliver and not doing. Thanks for nothing vodacom after how many years of been a customer with you. I am done with vodacom fiber dont ever get vodacom fiber for your house or businesses it wont work
