Poor service, I regret upgrading with them

Im so disappointed infact disappointed is an understatement this business decided to close both my lines whereas both of them were paid in full on the debit order date and their excuse was because i paid manually using the option they give us as customers VODAPAY APP now my account keeps on being tagged as being in arrears how can I be in arrears when I paid on the day of the debit order because I saw tht they hadn’t debited because my payday fell on the 25th so i decided to go ahead and pay manually thinking there was a mistake now i am being penalized for that on top of tht they asking me to pay a penalty fee for what when the payment was made the same flippin day and worst I called earlier to notify them of the payment when they kept on sending me massages that I was in arrears and they said my account was not in arrears, and I called them again to inform them that my line has been disconnected only for their agent to tell me my lines have been disconnected I must wait 2 to 5 hours which I waited but Still I wasn’t reconnected when I called again I was told by the agent that my line was not reconnected so whoever I spoke to **** 😡😡😡 to think I just upgraded with them makes me wanna puke and I won’t be upgrading my other line with them. To think i have been a loyal customer for over 3 years and this is the treatment I get 😡😡😡😡
