Two subscription for a single user.

Hi, my name is mohapi Molebatsi. I had a dstv before with my ex-wife and i'm now staying with another woman and i subscribe again and i realize later that i have two subscription under my name. I call the customer centre to cancel my previous account using my R100 airtime but after three days my account was closed again. We are paying a lot but we don't even have free customer service and the whatsapp account is useless. Why should i pay for two if i'm watching one? Does that mean my R100 airtime was to gain access for three days? we don't even have breakdown of all our transaction with them.
