Terrible terrible service

Since my contract started with Telkom in May 2019, I have problems. My account is never the same, although my contract is R338 per month. I need to load extra data bundles to access the Internet and WA. After many visits to Menlyn Telkom, many calls have still not solved my problem. Some of the excuses are that their switch from MTN network to Vodacom network does not reflect my payments because I do NOT pay with the App !!! but with EFT. Deduct their money through DO the amounts are never the same. First deduction was R1 111, and according to them it is for first month plus pro rata ?? Data and airtime simply disappear. Do you want to download something, network is constantly UNSTABLE. I have been getting the following message: internet access paused since about the beginning. Either yur data bundle is depleted or you are not in Telkom's coverage and using a Telkom only bundle. At the same time I get a message that says Hello! You have 15160 MB Telkom mobile data available. 4920 MB will expire on ... and the date. I gave the new banking details but the DO for end Feb hasn't gone through yet. They charge me re-connection fee every month because I paid via EFT. Last week after another almost 2 hours in total with Telkom, they cut me phone. I have asked several times for my contract, but still nothing!! numbers been affected is *** and ***. I had to get another sim and buy airtime and data to use. My daughter in law just called now telling me exactly the same is happening with her
