MultiChoice unAuthorized Price lock

hi

Saddened by Multichoice, in march I went to our local outlet in Soweto to downgrade the account we were paying at home, from Full-Bouque to a Compact-Deal. Two weeks later when I wasn't home someone from the "company" came to the house and instead brought the explora device and somehow convincing my mom that this is what I went to the outlet to do, and continued to install the device. When I got home on the weekend, realizing that something was amiss I we went to report what happened and discovered that rather than a downgrade we're now on a premium (price lock) of R999. We were told that since my mom is a pensioner this was not in anyway right and they will escalate the matter. well it is now August and I reported the matter in April since then R999 has been deducted from her account. I called again on the 14th of July and was advised that We should rather put her on the( compact price-lock) at R549.00 and that was fine with us. again my mother got a call saying she called in looking to insure her decoder. i was livid and warned her not to increase this account any further. So R999.00 was deducted yet again and this is frustrating when you can hardly afford most things in the house while Multi Choice has put a pensioner who stays alone on a price-lock of R999.

Help! I am running out of options here
