MTN BAD SERVICE

I am really not satisfied with the service received from MTN ONverwacht, Lephalale. My Samsung S9+ screen broke and I hand the handset in on 11 June 2019 to MTN Onverwacht to send it to Sansung so that I can receive a quote for the repair. After 2weeks on 25 June I went to the store to find out why I didn't receive the quote yet, only to hear that the phone was still in the safe with them. The only reason they can give me is that the Couriers didn't pick it up... really don't they do follow-ups????? I request them on 25 June to send the phone a.s.a.p because this phone is also my works phone and I am struggeling now with an old phone. I did report this to complaints@mtn and customer service but intil today I didn't even get an reply or call from them... and until today I still didn't receive an quote. The service is really BAD and there is no one who even try to help by getting my phone fix so that I can use my phone... Hopefully I will get response and assistance from you.
