paying subscription for decoder not working

I have a DSTV compact for more than 10 years and I always paid it around the 1st of each month. I app**** for price-lock as an additional decoder for my place as I left the original one at my mom's place. I have it now for 2 months and my debit order that gets deducted is for the price-lock and my mom's compact and I am happy with. I went to my mom's late on the 26th and when I got there her decoder is broken and she will need to get a new one. When I got to work on the 28th I called Multi-choice and requested for my mom's subscription to be suspended until I get a new decoder for and the agent confirmed that she will go ahead and do so. I called again now and I spoke to Charlotte and she tells me they can only suspend it after the 25th. In other words, my 75 year old mom will pay for something she hasn't used because she paid in advance? So if I didn't have price-lock like before I could have suspended her membership because I feel we are being used to pay for nothing. And I will go and reverse that debit order... even if it means I will not have access to my one. I might as well reverse and have someone else at my house to get a new dstv
