Terrible service and no communication within the company

Terrible service!!! I have a debit order for my cell c account. Payment did not go out so I received an sms and email to pay so I made a payment to them and called them on the 2 august to notify them, the consultant told me to send an email to proof of payments which I did and the next day cell took out the money from my account, I then reversed my payment and then an hour later got a notification that they reversed their payment. Called the call center again on the 4 august and they said that my account it up to date. On the 8 August my account was suspended and I called them again and they said that I had to make payment so I made the payment and sent an email to both customer service and proof of payment. On the 15 August I called them again as they did not unsuspended my account and the consultant said everything is up to date and they unsuspended my account. From the 15 all the way to today 23 august I have been getting calls from cellc that I did not pay. I spoke to multiple consultants and when I told them that I paid and they checked the system they confirmed that I was up to date. Today I called them again to confirm my payment as they tried contacting me again and was put through to collections as they said that I did not pay. The consultant asked me to send them my proof of payment to another email address and saw on the system that I did pay. There is no communication in cellc and the customer service is pathetic.
