Rain 5G - bad customer service

I have been with Rain for 5 years. I have just had a terrible experience when upgrading from Rain zero router to a RainOne 101 router and RainOne hone service. 1. I was not informed that the service was moving from post paid to prepaid. The result was a double installment that I was not expecting. 2. I was informed by the call centre person that they want my old router back. They expect me to sit around waiting for their courier to collect it. Why didn't they collect it when my new router was delivered. 3. The lady I spoke to was rude and abrupt, leaving me frustrated with none of my queries resolved.

If this is how Rain treats loyal customers, then I think it is time to change service providers.
