Poor service from Rain

I ordered the 5g sim card beginning of mMarch and the router plus sim card were delivered after 4 days. The wifi did not work immediately even though they claim it's a plug and play. I immediately reported this to Rain but got no response. I continued to use mobile data from a different network until 11 March 2023. I decided to inserted the Rain sim card in my phone the following day and I realized it was active. I sent an e mail to support several time to inform them but never got any assistance . Come 1st April, they attempted to debit R956 from my account and yet the subscription amount is R529. The debit order was rejected by my bank soon after that they disconnected my services. They attemped to debit over the next few days and the debit order was unsuccessful. I incurred charges from my bank because of the unsuccessful debit order. I sent a message to debit on the 15 the of every month yet I was ignored as always. I am very disappointed with the service I received from Rain and I will not be recommending it to anyone. I am going to cancel and only pay for what I used during March.
