Appalling vodacom

Vodacom is on a mission to destroy people’s lives. Took a contract for them ,firstly the phone started overheating...the lady at vodacom airways park firstly said ,they can’t do anything about it ,until another stuff member intervened to help considering my phone was only a month old,appalling. Then the following month they decide to debit my acc a week after the arrangement date.then they call to have me make arrangements as my account is in areas,as unimpressed as I was I did so then still they call me today to say the arrangement was not made again,the system doesn’t show,i almost missed my flight being on the phone with their consultant ,sorting out the date of payment with them,I’m thinking these people are messing up my credit scoring ,I’m trying to organize my life they messing it up ,do they know how hard it is to get housing loan ...I am disgusted...Vodacom is the worst,I regret taking a contract with them
