The Worst Client Service

I have a contract with your company for more than ten years, but lately it seems to me that vodacom Realy have the attitude that we dont care, on my upgrade last year Vodacom direct recommend, the sony Experia m4 Aqua as the best phone, it already cost me to go three times to kimberley to fix this phone, on one time the phone was send in for repairs, for more than a week now,i report to vodacom that my phone has no signal, but every time i must heard they are busy to resolve my problem and like i mention in my previous mail to them i used the phone as work related aswell, but its useless from thursday until now my phone is 95% of the air, and i promise if there is a problem again with this phone i will go and hand this phone in to your nearest shop and will do business with a more reliable provider, and my two other contracts that is due for upgrade in october will be moved to another service provider, so decided if you will be happy if i paid my account pro rata, because i will not accept this pathetic service from your company, and please the sony xperia is the most worst unreliable phone on the market, a phone of R 500, the qaulity is muts better
