Quick to suspend, but delays to reconnect

I have Cell C Fibre in my home. I cancelled my credit card as there was a ***** on it. Unfortunately this resulted in my fibre account going into arrears. I received an email from CFubre advising me if the arrears and saying the account would be suspended by the end of the month, however they suspended my account immediately. I made payment of the arrears and sent the proof of payment to the Email address they advised. I was advised there was no attachment, although I clearly attached the POP. I’ve sent the POP to 5 email addresses so far, everyone of them strips out the attached POP, and needless to say my account has not been reactivated. Cell C is very quick to suspend my account despite their own email saying it would only be cutoff at the month end, and once payment is made their processes and systems are so cumbersome to further delay activation of the account, and no support from the Cell C staff
