Poor customer service

Bad service. I app**** for the price lock in November 2020 due to my decoder being broken and i stated this during the application. On the 14th November it was installed but Dstv couldn't activate it bacause it was giving an error, on the 16th or 17 of November it was activated. On the 20th of November I was debited R505, December R1177. I called Dstv to query about the december debit order they told me that i was charged for a broken one because i didn't call a certain department for cancellation. I fought for my money back and i was refunded R306.90 on the 24th of December 2020, I was told that the other balance was going to be reversed as well but it was not done. On monday i called again 01 January 2021, the consultant told me that he can't reverse the amount its giving him an error he will escalate it to the price lock department and he will Cc me to the email but he never copied me to that email. Today I called and I was told that there is a zero balance. I need my R301 to be credited back, i cannot pay for something that was supposed to be cancelled by them during the application process as i stated that my decoder was broken. If the job was done right the first we wouldn't be here. My email is ***
