UNFAIR TREATMENT FROM EDGARS.

My complaint id with Edgars, my mom in law is a pensioner and she has this account over 20 years and never defaulted on any payments. last year my father in law was hospitalized and she contacted Edgars telling them what her dilemma is but is willing to pay half her instalments until such time that they can afford full payments. she called in November and a lady told her that she must pay a R1000.00 for 3 months and all should be fine. lo and behold all was sorted account was paid up and life should go on, when she tried to shop, they told her that her account is blocked. they told her to start all over again and she is also loosing all the benefits, such as her accidental benefits as well as her death benefits etc, we need help as this is not fair, just because she is a pensioner ( she paid this account freely every month no problems, just because she had a problem after all these years) she is now treated as a bad customer. where to from here.
