FED UP - ********* Contract/Debit deductions!!!

I've been having this same problems for over a year now... I have a R1090 contract and they still take off R1300+/month... Each time each agent gives me a different excuse. Then it's because they add tax and this little fee and that little fee and then when I ask them why was this not explained to me when I bought the phone they cannot answer. It's supposed to be a fixed contract. Even my little R99 contract they called me with now is being deducted by excess of R110/month! ***! I've logged sooo many queries and complaints and they just don't care. Bearing in mind this is MY TIME, MY ENERGY, MY SANITY, MY AIRTIME, MY PATIENTS being abused and tested each time I have to call. I'm slowly but surely getting rid of my contracts with them... Won't do business with them again. **************** and *********! They're employees are so desensitised to customer complaints they really don't care anymore, they don't even bother responding verbally over the phone anymore, I can sit there keeping quiet for ages waiting for the agent to answer or ask how they can further help me etc, but they don't, as long as they get their salary at the end of the month it's fine. It's the most rediculous thing I've ever seen. So many calls have been "escalated" with no feedback or call back!! There's no goal for customer service or customer retention there! GOODBYE VODACOM! YOU GUYS SUCK SO BAD!!
