Cell C pathetic

On 30 April 2019 I app**** for fibre at home with Cell C over the phone with a sales consultant. The consultant who assisted me told me that if I want to speed up the process, I must pay an amount of R799. I made the payment but were assured that the amount will be refunded to me immediately if the fibre is not approved. After a month (after not hearing anything from Cell C, I again phoned Cell C about 10x to find out what is happening with my application. Eventually I was told the application was declined. I requested them to pay my R799 back to me. It is now the 7th August and after numerous e-mails and many many many phone calls made to Cell C, I have not made any progress in getting my money back. If you owe Cell C money, they just cut your service. What can I do to get my money out of Cell C - except of course to spend hours on the phone trying to get someone to assist me. If I can give anyone advice, do not go to Cell C - they have pathetic client service. When you phone customer service, you hold on forever. I once held on for over 25 minutes! Stay away from Cell C!
