Poor phone and Wi Fi reception

I have been experiencing dismal intermittent both phone and wi fi reception since Mid December (in fact since April 2020 but with a Telkom router) and despite many and varied messages with William Makola at MTN since Jan 3 who is responsible for resolving reception matters, his subsequent apathy and total disinterest in finalising this matter is apparent. It bears mentioning that a new wi fi contract and MTN router was contracted wity MTN at the beginning of December. Despite the very friendly responsible MTN staff person at MTN Kolonnade (Belinda Lombard) and her e mail to various MTN staff on January 3 has still not resulted in resolving this matter. Evidently even MTN staff apparently ignore such communication from their own MTN stores. While there is a myriad of messages and voice mails, in summing up William finally delegated the task to Thomas on February 3 but to date (Feb 14) neither William and Thomas have reverted and simply ridden off into the sunset. MTN have dismally failed in resolving a customer's problem of many years standing due to a very indifferent attitude.
