Lack of customer service and no feedback

I took a cell c airtime advance for R15.00 sometime in Dec 2015 and I ported my Cell C number to Mtn before I could pay back the airtime to Cell C.<br> I started to get sms reminding me to pay back the airtime I took and I could not do that on the cellphone as I was now with Mtn .<br> I called Cell C and asked for their bank details and I paid back R20.00 on the 4th Feb as I was tired of getting sms reminders. <br> I was advised to send proof of payment to [Email Removed] and [Email Removed] which I did on the same day I made payment. I received a response \automated email\" to say a consultant will contact me with regard to this in 2 business days. <br> It is now over a month and no one called me - I get Smses every day to remind me that I am owing Cell C now for 88 days and I am sure they have also blacklisted me for R16.00 already<br> <br> What kind of a service is this ...? why send automated response to customers if you know no one will contact anybody back. <br> Can you imagine the smses I get sometimes as early as 5 in the morning to remind me that my account is now 88 days outstanding. <br> Can somebody tell Cell C to at least stop sending me Smses as it is starting to annoy me "
