No feedback - Pathetic Service

On 31.01.2019 I signed up for a Data contract with Cell C. On 02.02.2019 I received a call form an agent confirming my details and advising that my SIM will be delivered to me 04.02.2019. There was no reference provided. To date, there has not been a delivery to me. The contact center is absolutely useless!!! Nobody is able to assist and they continuously transfer you to other departments. Eventually I was told that my query is for the online department and that they do not have a contact number, somebody will contact me. This is absolutely ridiculous. I really wouldn't care if they did not already have my banking details. I am so sick of being thrown from pillar to post!!!
