3 MONTHS and still no response to my claim

MTN is probably the worst network provider i have ever come across. i have a contract with them and sent my phone in for repairs about 3 months ago early june and it was kept by the store for about 2 weeks and was then told that i should take the phone and MTN will collect at my house seeing that they were on strike. theafter i waited for about 3-4 weeks for MTN to collect the phone and they never pitched, soon after that people broke into my house and all our items were ****** including the samsung s4mini. we then went to MTN again to put in a claim and its now been over a month since and i havent heard anything from them. this is really nonsense as i have to keep using other peoples phones so people can contact me. i still have not been contacted and i went to go check and was told that thay will call us ( but they never do). This is really not fair on me as i have been with MTN for over 10 years and the rest of my family.
