Vodacom 12 month unsolved issue

12 month old unresolved overcharging query Please see attached file for full breakdown. To summarize: I had 2 contracts with Vodacom: a Nov 2017 24 month wifi contract ***) which expired in 2019, and a R350 airtime top-up on my pers phone ***). The 2017 contract expired and I was never notified, and monthly prem went up from R772.40 to R1387.75. After 3 months of calls, it was finally explained that on expiring, the charge automatically defaults to pay-as-you go rates. I went into Springs mall first week in March 2020 to cancel exp 2017 contract, and at the same time requested a new R199 wifi contact. I was told I still have to pay the R1387.75 end march, end April the new R199 fee will kick in. End April 2020 I am billed with R1007.76 and R248.99, total R1256.75. After numerous visits to the Springs mall shop (they could not or would not help me) (due to Corona calling was impossible) I discovered the following: there was a total mess up with the new contract, in stead of cancelling the 2017 contract, he connected it to my pers sim card, the ***, loaded the new 2020 contract to the 066 nr, correctly, and went and cancelled the R350 monthly airtime top-up (see invoices).I was unable to make this clear to the staff, and I was incorrectly charged for 5 months, April-August 2020 R1007.76 (R1007.76 x 5 = R5038.80) as well as the correct R248.99.I paid for x2 wifi contract whilst I only had on sim card, the ***, with x1 router and then my personal sim, on which I now got no airtime. After the how the how many ith visit to the shop, a call center consultant understood the problem and deleted the second wifi contract from my personal phone. BUT then AGAIN, end September, there is a mess up. The R1007.76 was gone, it was replaced, on still my personal sim card, with a R248.99 + R199 = R447.99!!! The amount of R248.99 is correct, but on the wrong sim no, and the R199 is made up of a R9.99 VAS call identity(?) and a R40 3G laptop installment?? To my above refund of R5038.80 there should be added R199 x 3 (sept, Oct and Nov), 199x3=597, bringing the refund to R5635.80. Then my last statement for Dec 2020 arrived and yet again, chaos: on my personal phone, the R248.99 disappeared now and is replaced with a R640.02 charge with reference 3G laptop installment. The 066 no is correct with R199 (but no vat?), total payment due end Dec 2020 R839.02.This R640.02 should be added to the refund due to me R5635.80+R640.02= R6275.82. I am a pensioner who still hold up a full time job everyday in order to survive. I have been a loyal customer of Vodacom for over 15 years and has always paid my account via debit order. I have acted on good faith and trust in Vodacom, by paying each month, although I knew the invoice against my account was irregular, I was assured that Vodacom will refund me. After 12 months I cannot let this go any further, I receive no help, no assistance. In fact, at my last visit to the shop in Springs, I was send to the police station to open a case of ***** against Vodacom, and if I come back with a case number, I may be assisted. Really? Beside the fact of the total irresponsibility of sending an old man into a high risk Corona area, this is clearly as case of gross incompetence and a high degree of unwillingness to help. I am begging somebody out there to please look at my case and sort out this mess. Donald du Preez *** / I***-2 (Account No)
