NON EXSISTING SERVICE FROM CELL C

I have NEVER heard back from Cell C ever! Not even responding to my emails. 6 Jan, 19 Jan 2023 I complained against them deducting an early debit order in December of which I had to carry the banking costs. I have asked them to pay back my banking cost as I phoned them and said that they cannot deduct early as my pay date AS PER my CONTRACT with them shows the 25th of the month. They are NOT answering me at all. Can someone help me with the Ombudsman's details as this is really pathetic service, been a LOYAL client for more than 15 years and this is how I have been treated. And then they reply on Hello Peter that they will be in contact with me - It NEVER happens!
