Bad service

My camera was expiring and I received an SMS notification that I must pay interest to Cash Crusaders Lambton. The SMS had a link that I must follow in order to make a eft payment online. Interest was R268.52 so I followed the link and paid the interest on the 29th of April. This was convenient for me since I have since relocated from gauteng to Mpumalanga, through the other months I have had to send someone to pay interest for me. Nonetheless I called in and was told the payment reflected on the system and the balance to take out was R3471.00. In my I received another notification that my item was expiring but this time there was no link, I called in and was told by a lady in the phone that it doesn't show interest to extend, however she said I can do capital Reduction which I'd pay R1850.00 and the balance (which the system would deduct R1850 from R3471) in 20 days then take out my camera. Since I'm far I was advised to use the detail I used the previous time. I made the payment 23 May and sent through proof of payment, but kept calling for weeks wanting to know what was my balance to take out my camera but no can assist me since today. Everytime I speak to someone new I'm told that they'll verify the payment, two weeks ago a guy said to me I need to pay R3500 to take out because the R1850 was just interested, when I told him I made an eft payment he said he doesn't know what to do about that and he'll tell others to call me but nothing. I'm afraid next thing I'll be told my camera was sold, I've just wanted my camera back but the interest keeps going up to my expense unnecessary. I sent my relative a month ago but she was told I must pay R3500 to get my camera back because R1850 does show on the system, yet one lady I spoke to told me that they recognized the payment and she'll check for me the balance soon s it shows on the system. I am unwilling to lose a R20k camera over this please fix it.
