Cancelled contract but RAIN keeps on charging me for months

I struggled for almost a month to cancel my contract with RAIN 5G because RAIN has NO WAY for customers to contact them. Finally I succeeded (so I thought) and they picked up the 5G modem. They have continued to charge me R1000/month for two months since I cancelled the contract, and the contract still shows as active on the RAIN website. As usual - there is no way to contact the company directly and I rely on HelloPeter and the MyBroadband Forum to get RAIN's attention. This is shocking - and very likely ******* behaviour on the part of RAIN.
