Miscommunication by service provider

I have been a dstv customer for sometime and never have I ever imagined being so disappointed. I recently changed dwellings and had not installed my dish at the place I stay at now. I got an email and sms's that if I reconnected my service by the 31 March 2021 i'll save R119.Little did I know this was too good to be true, I then got a follow up sms that I needed to pay R140 I logged a query and that was cleared given I provided my email as proof. Today I get an sms that my service was disconnected and have to pay R251. I paid over R500 for a compact subscription due to "miscommunication" as mentioned by your agent whom I vented to on Facebook. I must say this was an experience I will certainly never forget.
