Arrogant Landlord

When teanants signed their contract here, property management told them that there is DSTV connection, which is true except that in the past 10 days there was no signal in the complex and we could not watch tv except that we pay premiums of up to R1000. The ****ty management keep on lying and ignoring teanants about the matter. The worst part is that there is nothing that teanants can do to solve this problem individually as we live in a complex. What measures can one take to get this Landlord to account and refund teanants their premiums money as it is not their fault ?
