Absolute poor Service from Rain

I have had Rain for the past 2 years going on 3. My experience with them was okay at first then started getting worse with time. I had no Fibre available in my arear up until recently and as soon as it was available I app**** and had this installed in the Month of June. I cancelled my Rain month to month subscription during the course of the month (before the end of the Month) and the payment went through at the end of the month which is only fair as I used this service during the Month. I was then billed again for the Month of July. Took this up with them and the agents over email seem to be so stupid in resolving issues and respond with the same thing but cannot answer my question. This Service is the worst and I strongly recommend you rather opt for Fibre or go with a different provider such as Telkom or Cell C whichever has better coverage in your area. The overall experience will be more professional and reliable.
