Poor service

I signed up with Chase Tracking 3 years ago. Before I signed up, they offered me a package for R109. since I didn't know the company, I decided to to go online to check them out. I realised that the package they had offered me was advertised on their website for R 99. I told the sales consultant that I was not willing to pay R 109 for a package of R 99 and I would sign up on the condition that I will pay R 99. of which they agreed. From the first premium they went back on their word and billed me R 109 for a period of about 2 years. After 2 years with them, I went on their website and the same package was still advertised for R99, I then wrote them an email and was assisted by Lakeisha Michaels, who assisted me to rectify my premium from R 109 to R 99. I asked about what would happen to the extra money that i was billed, and she said I would be refunded, she just needs to escalate the matter and give me feedback as soon as she has received it. I made numerous follow ups and everyone says they will escalate the matter and give me feedback. till today they are still escalating the matter and returning to me as soon as they get feedback.
