No help from DSTV

My husband passed away in January, I have been trying for two days now to contact them to change my account from his details to mine. Had to get my son in law to pay my account as they suspended my account due to my husband's bank account was closed due to his estate being wound up. The two telephone no's given do not work ie *** or ***. The whatt's app is an automated response which is not help at all. Tried to get the bank details on line, no help either.
