Pathetic service from clueless staff

Signed up with Rain yet again in May 2024 after previously being disappointed in 2020 and cancelled. When I went, I was told I owed R500 from my previous account with them which I paid. I was issued a new router and paid the pro-rata amount.

I paid my monthly fee of R595 on the 1st June as per the contract and my line was cut-off after I paid. I logged on to their portal and was told I owe R118 which I also paid to get the line reconnected.

I've since been calling and dealt with 3 people from their accounts who all do not have a clue why I'm being billed additional amounts. The one says my previous account is active, which can't be true because it was cancelled in 2020. The other 2 clearly had no idea and 40mins into the call asking me to hold while they investigate, they both eventually hung up on me.

These companies usually assist when you come on here and detail your frustration so I'm trying my luck too before cancelling my account yet again.
