Sick and tired of being bombarded with calls !!!!

I have been a customer of vodacom for many years. In Sept. I took out a new contract. For some reason the first payment bounced, my fault I know.....that time of the month.<br> <br> After getting the first automated call from ***7 I contacted the customer care and made an arrangement with them to debit my account as soon as possible.<br> <br> I am still being bombarded by as many as 15 calls and some sms's to all 4 my numbers, being used by my parents and in-laws. I am looking like a total loser.<br> <br> I do get that it started with me, but come on VODACOM....I told you to debit A.S.A.P !<br> <br> I kind of feel like ditching the contracts and go somewhere better !
