****ed up service

My contract was cancelled on Wednesday 29 Nov 2017 and my network wasnt available. I gave them a call the next morning and in return was told they need to advise MTN to transfer it back to Prepaid and should be fixed within 48 hours. Monday 4 Dec 2017 my network is still not available, I call them and they tell me MTN is delaying. I call MTN who advise me that One2One actually needs to transfer the number to Prepaid as the contract was with them. I had Data on my phone which expires today as the contract was Top-up. I obviously lost it now but most importantly I am expecting important calls on my phone this week but these ****s are just *****ing me over.
