UNPROFESSIONAL AND UNSATISFYING CUSTOMER SERVICE

I have a cell c contract , they suspended my account due to outstanding payments ... I DID NOT receive any sms's or emails nor phone calls regarding a issue with my contract. Went to Tygervalley centre, so they told me I am outstanding February and March 2022 but I have the ALL my cash slips proof of payment, then they said again I am outstanding September and October 2021 - NOW they telling me I am outstanding July 2021 BUT I have the proof of payments for all these dates - the customer care people is so impolite and unprofessional, it is ridiculous - I need my phone connected so that I can work , atm I have no access to my cellphone AND IF my account is "outstanding" WHY weren't any contact made with me , and why didn't Cell C tell me there is a outstanding amount, but they want to do it Now ????? I have 3 logged complaint numbers but getting no feedback!!! I am 5 different dates im given , this is dishonesty and **************** - I see no point in a contract with Cell C - my data runs out by the 5th of each month then I must buy data which is expensive - worst is I have wifi at home so where is my data disappearing to ????
