Debit order issues

I have never had any issues with Cell C Now I am so frustrated with the Whatsapp chatbot Kelly I have had a contract with Cell C for very long now and I used to pay my account each month, I did not set up a debit order, as it helped me when payment came in on different days Now, the Kelly on the Whatsapp chat kept bothering me with setting up a debit order I recently started working at a new company and also changed banks I kept having issues with the debit order that could not deduct and then had to pay R70 extra the next month After the second time of this and giving my correct details through, I spoke to someone at Cell C and she did try to assist me best she could It kept erroring by the mandate. I then thought to ask her just to check and confirm my bank details as I had the feeling something was wrong And yes, after I gave through my correct details like 3 times to the chatbot and again over the phone to Cell C previously, we noticed that the account number was incorrect She then tried to change it and got an error, as my bank account is not yet open for more than 3 months, so I have to call again when I have had my bank account for 3 months Now Kelly started with me again and asked for the correct details, after I tried to explain the situation Also having to keep repeating this whole situation every time is tiring and frustrating I feel that all this extra I have had to pay, should be reimbursed as it was not my fault and how it was not picked up when they tried to add my details, as it was picked up with the last call, that 1st person might just have felt that they don't want to handle it and now I have to pay the price Also, it's not like I have only been a client for a few months, I have been one for a few years, more like many years I am not one to complain, especially publicly So maybe something will be done and nobody will have this issue again in the future
