Struggling to get the total balance on the telkom account

So my husband took out a contract with Telkom which was canceled due to skipped payments and then they called him and he made a arrangement with them which he stuck to to avoid ruining his credit record so now when he contacts telkom to find out the balance owing so he can know suddenly no one can assist him except for the collections department who happen to not have a contact number but an email address, he wasasked by different call center agents to provide bankstatements as proof of all the payments made but when they suppose to contact him for feedback they can't collections has to do that, some agent gave him collections Dept email address to send the querie to along with bankstatements but no one has bothered to contact him so they can tell him the total owing to Telkom....

Telkom is very quick to call you when you skip your payment but as soon as you want assistance they no where to be seen or found, all he wants is the balance so that he doesn't exceed the total amount owing.
