No connection even though account shows up to date

Very disappointed with Rain's service. I arranged for a weekly promise to pay and paid the amount of R130 as requested on a Whatsapp conversation yesterday, but our internet connection was never reconnected. The account of the Raingo website shows we are paid up to date on both Promise to Pay and regular account. We tried to contact them numerous times (on website and Whatsapp) with no luck. We also tried to phone the call centre three times, and held on for 15 minutes each time with no answer. We need this sorted as soon as possible please.
