We recoverd it back in Kwa Thema and since 25 August I try to UN-BLACKLIST the phone.<br> On 26/8/2015 I went to Mall @ Carnival they fax the Un blacklisting form, my id copy and affidavit. I phone after 2 weeks and Cell C told me they havent received my forms. On Saterday 5 Sept my Son hand in the forms (with a new affidavit that I needed to go and get again.) on 10 Sept I phoned again and again my forms is not received.<br> <br> I try to email fax it 7 times on ***9 and *** I only get communication errors. I email the forms and today 11 September 2015 I phone to get feedback and again they could not help ME... <br> Please I need to get this phone UN-BLACKLIST.
