Is it possible to give a minus rating?

So surprise - still no resolution (7 days later) to the matter of my contract being cancelled more than 30 days before the date I recorded on the cancellation form. This after talking to someone from the Social Media Department who advised that a call would be logged with the technical team as they would have to look at the exact amount of data still available when the account was incorrectly cancelled. They further advised that they would credit me for the days that I had paid for that the account was not active and they would call tomorrow to update me........ I'm almost sure when you use the word "tomorrow" that means the day after the day you had contact. I could be wrong so perhaps I need to check the definition of "tomorrow" in whatever book of definitions that will tell me that it actually means "never"! Shame on you Cell C - this mistake was made by your staff. The very least that should have been done was to resolve the issue as soon as possible and take responsibility for creating a great deal of inconvenience for one of your customers. Clearly in this instance the customer is not king but merely an irritation to be ignored in the hope that it will go away. Not only have you lost a customer who may have come back to Cell C in the future but this customer will definitely not be recommending Cell C to anyone.

BTW - "tomorrow" means the "day after today"! Oh and further BTW - I paid for this month so Cell C owes me for the early cancellation..........
