Really bad customer care

In December my Router was ******, on contacting RAIN to explain my problem, I was promised a new replacement SIM card. The day RAM delivered my replacement SIM card, I never had all my documents that were required. Once I had all documents I made arrangement for RAIN & RAM to re-deliver my SIM card but before 21 December 2021 as I was going on leave. NO delivery came in time. Received a call while on holiday RAM wanted to deliver my SIM card, informed RAM & RAIN that I would be back in JHB on 11/1/2021 to accept my delivery. In January I got informed by RAM that they destroyed my parcel. Now all of a sudden I must pay RAIN for my replacement SIM card. NOT the original amount,I paid when I started with them but the FULL subscription amount for a month. I am so unsatisfied with RAIN and they have no way how to treat a customer, You always seem to get computerised responses, like no one takes the time to read your communication you get.
