Sick and tired of Cell C *****ing from us

I recently updated mine and my husbands contract at Cell C The Glen and the VERY FIRST thing we asked the consultant before making any decisions was if the minutes in our contracts would role over every month. We were assured they would and took their word for it since we have been with Cell C for many years now and rolling over of minutes was the norm. We however have noticed that our minutes are not rolling over so I called Cell C to enquire and they told me to speak to the branch at the Glen who made the promise. I've been at this for 3 weeks now trying to get this sorted and fixed up as it should be but am getting very frustrated with the lack of response I am getting. I try call Cell C at The Glen like 6 times a day but it's so difficult to get through, or if I do get through, I'm told the consultants are busy. We already get such few minutes on our contract and on top of it you ***** the left over from us at the end of the month. Sick and tired of continuously fighting with Cell C for what is rightfully ours. This is not the first time we have been let down by Cell C - ENOUGH is ENOUGH!
