I am upset and VERY UNHAPPY with them

I am upset and VERY UNHAPPY with them. Together with their attorneys at VVM. I fell behind with payments and made an arrangement with VVM. They told me that my line will stay closed until i have settled the account. Vodacom said they cannot help me with the account until it is settled. So. I started paying off the debt. Asked numerous times if they could please help me with the line. Open it as a prepaid so that i could still receive calls. They said no way. They cannot assist me. Now they have given my number to another person although i still use the nr on whatsapp. Vodacom say they cannot do anything because there was no use on the number and i have not reloaded with airtime. Wich i could not do as the nr was blocked. So now everybody that tries to use my old nr reaches the new owner. I am furious. They have promised me to unblock my nr as soon as i have settled the account.
