Monopolised enertainment

Since Dec2020 I've been having problems with my Explora. It displays messages that the hard drive is ******* and requests that the hard drive is reformatted or the Explora would lose its full functionality. Eventually after several e-mails and attempts to resolve the problem remotely, I was advised to take the decoder to a MultiChoice branch. I did, around 23 Dec 2020. I spent 4 hours queuing before receiving service. I was told by the rep that the hard drive was ******* and the problem was fixed. It worked for a few days and then the problem started again. I was advised to take the decoder back to the branch where I was told the hard drive was again *******. I was given options and chose to swop my decoder for a reconditioned one. It cost R600-00, came with a 3 month warranty, effected on 2 Jan 2021. It also cost a further 4 hours of queuing. Over the last 6 weeks, 4 of those being on a Sunday, the problem has again returned. After a day or two the decoder would un-******* itself and full functionality would return. Since 16 March 2021 to date normal functionality of my Explora has been lost. I must add that these problems started in Dec 2020 after numerous tele-sales calls promoting the sale of the latest Explora, which I declined. I am not IT savvy but I don't know how a hard drive can be ******* and later un-******* itself.
