Poor service

We bought data for office router, *** for R199 on the 28th December 2022, which was 80G. 40 day and 40 night. We did receive a confirmation sms that it was bought.We even checked the balance it was there. We used it for 2 days and it stopped working. We called Cell C on the 3rd of January and we were told to wait for 48hrs as our matter has been escalated (case no: ***). They acknowledged that they had a technical glitch on the day we loaded the data. Today we called again and spoke to a consultant she said the matter has been escalated but the hours for resolving the matter has been extended,for how long we don't know. We called again and asked to speak to one of the supervisors. I spoke to Sarah she insisted that we used airtime instead of data as Cell C had a technical glitch,however there is nothing they can do about it. Even though the facts were right infront of her eyes, she didn't care and she insisted that it was our doing and not Cell C. I tried reasoning with her without success and she cut the conversation by saying "is there anything else I can help you with besides this?" I had no words. Why am I taking the blame for Cell C's mistake?
