No communication, and still selling telecoms

Hi <br> <br> As stupid as it may sound, I'm selling Telkom LTE services through my business to my customers. All these contracts are linked to my business account. For there months in a row now all my accounts gets suspended if one of my clients don't pay. So 1 will pay and the other won't the Telkom finds it in order to switch of both accounts. I have even phone the call centre to suspend the ones that don't pay, but even that is not enough for Telkom to keep the other services active...<br> <br> Thank you Telkom, if it wasn't for you everything would be great in my life!!
