Double billed for a mistake Rain made with their employees!!! Insane.

On the 29th of September I decided to switch my then current 4G unlimited plan to the at the time 5G basic plan for R499, the sales department at Rain called me to confirm my delivery and it arrived Monday on the 3rd of October, Upon delivery I get given two 5G WiFi routers I tell the delivery guy I didn't order two and he explains that no worries they will come and fetch it if you don't use it. Same day (on the 3rd of Oct) - I open a support ticket to enquire about the extra WiFi router, and they get back to me on the 15th of October via phone call Very professional and friendly guy calls me and asked me all the questions about connection wise I confirm with him that it's all good so far and we now discuss the extra WiFi router and I tell him that I didn't order it I switched to the basic plan and he said he understands and he tells me right then and there he would cancel it for me and I will only pay my bill on the 1st of December because I'd already gotten deducted from the 4G unlimited plan so November payment will be on December we agreed upon the cancellation of the other router and on the 25th I received an email from rain support Telling me the Ram courier services are going to be collecting the other router and sure enough around 3-4 PM they arrived I give them the WiFi router and they hand me a sticker with a reference number: COL17******* . I'm under the assumption that it's cancelled and I don't need to worry about anything until December fast forward to the 1st of November and Rain try to double bill me for R1128.42 but luckily my card limit for online purchases was not allowing to get ****** by Rain Today is the 8th of November and they still trying to auto bill me the amount I phoned them with my airtime I was put on hold for 13 minutes waiting for a response from an assistant and when he finally took my call I explained to him that I am being double billed for something I don't possess and for a 5G plan I didn't order and explained to him that it was supposedly cancelled immediately why am I still being billed for it, he tells me it says I have two plans active and he said the matter would be escalated to the relevant department at rain this was on 3rd of November they never called me back like they said they would in 24 to 48 hours it's been 3 business days now and 5 If the weekend is involved my WiFi has been cut from connection right now I didn't get any response - no phone call, no email nothing Since the 3rd Of November about the situation I called them this morning my airtime even cut out before I got through the hold music. This was truly the final result of everything a very bad review because i have been patient with them now I'm really fed up with Rain This is a very bad way to conduct business with paying customers especially on a mistake your employees made I'm expected to pay for their mistakes?? Won't happen 1st of December Is what I was told I'd be billed and that's what I am sticking to I did no wrong here. Rain internet provider fix this !
