Data Roaming charge of R45 000 for 273 mb

Good Day. I have made numerous calls and sent emails to sort this issue out. On 25 and 28 February I spoke to customer care and was assured that I would receive a resolution and proof that I requested data roaming within 48 hours - your automatic response to emails sent states this. I never had and never requested data roaming and was assured if this is not the case I would be provided proof and could listen to such on the phone as I am out of the country. I never paid a deposit as required and had never used international data since I first ported the number to Cell C. In the last email, Incident: ***, I have explicitly stated that if this is not resolved with in the next 48 hours I can take it that Cell C does not have proof and will forthwith reverse all charges. Cell C please provide confirmation within 48 hours that the charge will be reversed if you do not provide proof that I can verify within 48 hours that you agree the charges will be reversed. My current contact details are available on all emails and can be obtained from discussions with call centre.
