Lack of customer services at Cell c

I was offered a contract by cells of 20gigs per month and asked the agent to lock the account so that I don't go over the agreed offer my words were "I don't want anything more or less I just want to pay R199" that can be even listened to the recordings.to my surprise I kept on paying huge amounts monthly and I thought I was also paying for another contract that I had with cells that was going to expire on the 7th of November to my surprise when I requested the statement the Nov contract was cancelled but my line was opened and I asked the consultant that was handling my query last month he said my line is open,I have been calling cell c call centre,they of no help shame I must say they keep on giving you reference numbers but nothing changes,the last consultant said I will be refunded since the mistake of the open line is on their side but they will credit my cell c account and will not pay me to my bank account.Below are some of the reference numbers; ********** ********** ********** 51182 on 08.11.2 ********** ********** 13562 on 13.11.2018 On all of the above no one come back to me.In Sept R1 857.70, October R1 802.08 and Nov R1 441.97 which is supposed to be R1 065.96 of which an amount of R1 903.87 is due to me.I just want my money in my bank account before the 7th you have my bank details.Today your call centre does not have network I have tried calling you twice since you don't have a courtesy to resolve my issue.
