Clearly Im wasting my time seeing all the complain

Clearly I am wasting my time, looking at the amount of complaints. My account has been messed up since February this year. Every 2nd week my account gets blocked stating I am in arrears. Once upon a time when the call centre were still actually working, I was advised my account is in fact in credit and all will be sorted out. June I have 2 different debit orders running through my account. I went to Cresta and again I was told the problem came into effect when the debit order date was changed from he end of the month to the 20th of every month. Friday my account was activated again and I was advised by manager at Cresta branch that he will escalate it to Credit to sort out. Monday night my account gets blocked AGAIN !!!! How many times do I have to go through this. I am so sick of this. I am really calling Cell C today and moving my account of more than 14 years to them. At least their service their clients
