False advertising and poor customer service

False advertising and poor customer service. To my extreme disappointment and not being able to do anything about it is very sad and fustrating. My partner and I decided to take a contract with Cell C for fibre to the home with the special that they offered ( three months free) which was not given to us after numerous calls and emails the debit order which was not supposed to ve deducted was taken. It seems as long as they have a contract in place and they have authority to debit your account nothing else matters. As long as your signature is given you are just a number to them no after sales service. At this point I am tired of calling them as I dont have a cell C phone my phone bill is extremely high. What choice do I have but be manipulated by them,an not be given what was promised.
