Not Honouring Discount Offered and Billing Error

As a first time user I left a wonderful review just a week ago regarding Rain Networks only to be disgustingly disappointed by Rain's actions less than a week later . Firstly the discount I was promised was never app**** and when I state this nobody seems to know why the discount was given but it was your agent Fanekhaya (Reference Number: ***7) who gave me that discount without prompting. Now Rain decides to bill me twice for a R649 router and when I send them the proof of this to their billing email nobody acknowledges receipt of this email or even gets back to me for the way forward. As for calling the call centre waste of time and patience as they do not know anything, they tell you the same thing over and over and without fail the call goes quiet then "Goodbye". What kind of establishment are you running honestly. You seem like you are offering the best service out there but you are turning out to be the opposite. Highly disappointed.
