Do better showmax/dstv

I have been paying my subscription for showmax through dstv for months. Since the new app I cannot connect to showmax. I checked with dstv and they said my account is active and up to date. I have been in touch with showmax and was told I need to change my billing date at dstv. Back to dstv who say they can only change my billing date end of March. Is this the kind of service you give customers since the new app? To tell me I need to go to a dstv walk in center for a problem on your side?
