Extremely unhappy client!!!

I currently hold a contract with Cell C Account no. ***. My account has always been in credit since 2019 until today.

My last two months of trying to resolve my "NO WIFI" on my ****le has given me untold frustration. No-one is willing to solve my problem. I had no wifi last month and this month once again I have no wifi, yet the amount has been deducted on my account. Now either Cell C reimburses me the two months wifi or with immediate effect I end my contract with Cell C. Now I would think under these times that every corporate would want to retain its clientele however not in this case has I have had no service excellence from Cell C at the Malls who simply say they can do nothing to assist which I find utter nonsense.
